Step-by-step explanation:

To work out x, we have to use the following equation:
x= -b± √b²-4ac /2a
Working out:
b²-4ac = 2² -4×3×(-4)

What she needs to score on test 4?Let's say that she scores X on test 4, if she wants to have an average of 71.5%, then we can write the equation:
(77 + 54 + 86 + X)/4 = 71.5

Answers
The unadjusted trial balance of The Lexington Group as of May 31, 20Y6, contains errors resulting in an unequal debit and credit balance of $27,875.
The unadjusted trial balance is a statement that lists all the accounts and their balances before any adjustments are made. It is used as a starting point to prepare the financial statements. In this case, the unadjusted trial balance of The Lexington Group shows a debit total of $608,125 and a credit total of $636,000, resulting in a difference of $27,875.
The errors mentioned in the question are the reasons for the imbalance. Let's go through each error:
1. The cash entered on the trial balance was overstated by $7,000. This means that the cash balance is higher than it should be by $7,000, resulting in an inflated debit balance.
2. A cash receipt of $8,200 was posted as a debit to cash of $2,800. This error resulted in an understatement of the cash balance by $5,400.
3. A debit of $16,500 to accounts receivable was not posted. As a result, the accounts receivable balance is understated by $16,500.
4. A return of $125 of defective supplies was erroneously posted as a $1,250 credit to supplies. This error caused an overstatement of the supplies balance by $1,125.
5. An insurance policy acquired at a cost of $3,600 was posted as a credit to prepaid insurance. This mistake resulted in an understatement of the prepaid insurance balance by $3,600.
6. The balance of notes payable was understated by $9,000. This means that the liability for notes payable is lower by $9,000 than it should be.
7. A credit of $10,000 in accounts payable was overlooked when determining the balance of the account. This error led to an understatement of the accounts payable balance by $10,000.
8. A debit of $5,000 for dividends was posted as a credit to retained earnings. This mistake caused an understatement of the dividends and an overstatement of the retained earnings by $5,000.
9. The balance of $60,300 in rent expense was entered as $63,000 in the trial balance. This error resulted in an overstatement of the rent expense by $2,700.
10. Gas, electricity, and water expense, with a balance of $16,350, was omitted from the trial balance. This omission caused an understatement of the total expenses by $16,350.
When we analyze the errors, we find that some accounts have been overstated, some have been understated, and some transactions have been completely omitted. These errors have led to an imbalance between the debit and credit sides of the trial balance.

Answers
The given sequence is arithmetic, with a common difference of -4. The first four terms of the sequence are -8, -12, -16, and -20.
To show that the sequence is arithmetic, we need to demonstrate that the difference between consecutive terms is constant. Let's calculate the difference between \(\(C_n\) and \(C_{n-1}\):\)
\(\(d = C_n - C_{n-1} = (-8 - 4n) - (-8 - 4(n-1))\)\)
Simplifying the expression inside the brackets, we have:
\(\(d = (-8 - 4n) - (-8 + 4 - 4n)\)\)
Combining like terms, we get:
\(\(d = -8 - 4n + 8 - 4 + 4n\)\)
The terms -4n and 4n cancel each other out, leaving us with:
\(\(d = -4\)\)
Therefore, the common difference of the sequence is -4, confirming that the sequence is indeed arithmetic.
The first four terms of the sequence, \(\(C_n\),\) are -8, -12, -16, and -20.

People use water to cook clean and drink every day . it is estimated that 16.8% of the water used each day is for cleaning. if a family uses 67.2 gallons of water per day for cleaning how many total gallons do they use per day
Answers
400 gallons of water are used everyday.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
Percentage of water used for cleaning= 16.8%
Gallons of water used for cleaning= 67.2
Let the number of gallons used everyday be represented by g. Then,
16.8 % of g = 67.2
16.8/100 × g = 67.2
0.168 × g = 67.2
g= 400 gallons

how much further will the spring stretch if a 0.60 kg block is added to the 1.2 kg block?
Answers
The spring will stretch 1.5 times further when the 0.60 kg block is added to the 1.2 kg block.
To determine how much further the spring will stretch when a 0.60 kg block is added to the 1.2 kg block, we need to consider Hooke's Law, which states that the force exerted by a spring is directly proportional to the displacement from its equilibrium position.
Let's assume that the spring is initially stretched by a certain amount x when only the 1.2 kg block is attached. The force exerted by the spring is given by F = kx, where k is the spring constant.
When the 0.60 kg block is added, the total mass becomes 1.2 kg + 0.60 kg = 1.8 kg. The force exerted by the spring remains the same, but the total mass affects the acceleration of the system according to Newton's second law, F = ma.
Using F = ma, we can find the acceleration of the system: F = (1.8 kg)(9.8 m/s^2) = 17.64 N.
Since F = kx, we can rearrange the equation to find x: x = F/k.
Now, if we assume the spring constant k remains constant, the displacement x will increase by a factor of 1.8 kg/1.2 kg = 1.5.
Therefore, the spring will stretch 1.5 times further when the 0.60 kg block is added to the 1.2 kg block.

On a number line point is located at 2, point c is located at 5 and points b lies between points a and c what is location of b such that the ratio of ab :bc is 1:3
Answers
The location of point b n a number line with a point is located at 2 is 2.8.
What is ratio and proportions?According to the idea of ratio proportionality, two ratios are proportional if they are equal. To put it another way, if a/b = c/d, then an is to b what c is to d. Several branches of mathematics and science, including geometry, physics, and statistics, all make use of this idea. Also, it is useful in daily life when comparing product costs or figuring out cooking ratios.
Let the location of point b = x.
Using the ratio and proportion we have:
ab/bc = 1/3
Substituting ab and bc in terms of x we have:
(x-2)/(5-x) = 1/3
3x - 6 = 5 - x
x = 2.8
Hence, the location of point b n a number line with a point is located at 2 is 2.8.

The length of a rectangle is three times its width. The perimeter is 72 inches. Answer as L x W
Answers
Answer:
Length = 14.7 inches.Width = 4.90 inchesStep-by-step explanation:
It's given that,
The length of a rectangle is three times its width.
Let width of the rectangle be x and Length of the rectangle be 3x
Perimeter of yhe rectangle is 72 inches.
Area of rectangle is calculated by,
area = length × width
3x × x = 72
3x² = 72
x² = 72/3
x² = 24
x \(\approx\)4.90
Hence,
Width of rectangle = 4.90 inch
Length of rectangle = 3x
3 × 4.90
14.7 inches.
Hence, Length of the rectangle is 14.7 inch and width is 4.90 inch.

Find two consecutive positive integers such that the square of the larger integer is 19 more than 9 times the smaller integer define your variables and write an equation HURRY HELP PLEASE SHOW STEPS
Answers
Answer:
9 and 10
Step-by-step explanation:
x = 1st positive integer
x+1 = 2nd positive integer
Solve for both x and x+1(x+1) is the next positive integer after x (Ex. 3 aka 2+1 is next integer after 2).
Larger Integer: x+1 ==> being squared
Smaller Integer: x ==> being multipled by 9
9x + 19 = (x+1)^2 ==> the square of (x+1) is 19 more that 9 multiplied by x.
9x + 19 = (x+1)(x+1) ==> simplify
9x + 19 = x(x+1) + 1(x+1) ==> distribute (x+1) to x and 1.
9x + 19 = (x*x + 1*x) + (1*x + 1*1)
9x + 19 = x^2 + x + x + 1 ==> simplify
9x + 19 = x^2 + 2x + 1
19 = x^2 - 7x + 1 ==> subtract 9x on both sides
Make one side of the equation equal to 0 so you can factor the equation:
0 = x^2 - 7x - 18 ==> subtract both sides by 19
0 = x^2 + 2x - 9x - 18 ==> 2x - 9x = -7x and 2 * (-9) = -18
0 = x*x + 2x - 9x - 18
0 = x(x + 2) - 9(x + 2) ==> factor
0 = (x - 9)(x + 2)
x - 9 = 0 x + 2 = 0
x = 9 x = -2
Out of x = 9 and x = -2, only x = 9 is positive.
Hence, x = 9 and x+1=10.
Hence, the answers are 9 and 10.
