The fully factored form of 2x^2 + 10x - 12, both through grouping and factoring out the GCF, is 2(x + 6)(x - 1).

To find the greatest common factor (GCF) of the expression 2x^2 + 10x - 12, we need to identify the largest common factor among all the coefficients and variables. In this case, the GCF is 2.

To rewrite the expression with four terms, we can factor out the GCF from the first two terms and the last two terms. Here's the breakdown:

2x^2 + 10x - 12

First, let's factor out the GCF, which is 2:

2(x^2 + 5x - 6)

Now we have the expression written with four terms: 2x^2 + 10x - 12 becomes 2(x^2 + 5x - 6).

To factor the expression further using the method of grouping, we need to find two numbers that multiply to -6 and add up to 5 (the coefficient of the middle term, 5x).

The numbers that satisfy these conditions are 6 and -1 since 6 * (-1) = -6 and 6 + (-1) = 5.

We can now rewrite the middle term (5x) as the sum of these two numbers:

2(x^2 + 6x - x - 6)

Now we can group the terms:

2[(x^2 + 6x) + (-x - 6)]

Next, we factor out the common factors from each group:

2[x(x + 6) - 1(x + 6)]

Notice that both terms in the brackets have a common factor, which is (x + 6). We can factor it out:

2(x + 6)(x - 1)

"r" has a value of 3.24 when s = 5.

Given : r=15 when s=3

To Find: The value of r when s=5

Solution: When one item changes for a specific occurrence and the other changes as a result, there occurs a phenomenon of contrast, which is known as being "inversely proportional".

Now, if we assume that c is constant, and r changes inversely as the cube of s, we have:

⇒rxs³=c    [to follow the inverse proportion assuming that we use a constant "c"]

⇒c=15 x (3)³   [r=15 and s=3 values substituted]

⇒c = 405

Find the value once more for the second example.

c will be 405 for r when s=5 since it is a constant.

in order to write:

rxs³=c

→ r=c/(s)³

⇒ r=405/3 [ As the values of c=405 and s=5]

⇒r=3.14

Therefore, r has a value of 3.24 when s = 5.

Given statement solution is :- The equation of the line perpendicular to y = (1/3)x - 2 and containing the point (-2, 6) is y = -3x.

To find the equation of a line perpendicular to the given line and passing through the point (-2, 6), we need to determine the slope of the perpendicular line.

The given line has a slope of 1/3. The slope of a line perpendicular to this line will be the negative reciprocal of the given slope. So, the slope of the perpendicular line will be -3/1 or -3.

Now, we can use the point-slope form of a linear equation to find the equation of the line:

y - y1 = m(x - x1),

where (x1, y1) is the given point and m is the slope.

Using the point (-2, 6) and the slope -3, we substitute these values into the equation:

y - 6 = -3(x - (-2)).

Simplifying:

y - 6 = -3(x + 2).

Expanding:

y - 6 = -3x - 6.

Now, we can rearrange the equation into slope-intercept form (y = mx + b):

y = -3x - 6 + 6.

Simplifying:

y = -3x.

Therefore, the equation of the line perpendicular to y = (1/3)x - 2 and containing the point (-2, 6) is y = -3x.

I'm not sure if it's correct

To express the confidence interval 0.252 ± 0.044 in the form of p - e, we need to determine the center point (p) and the error margin (e).

The center point (p) is the middle value of the confidence interval, which is 0.252.

The error margin (e) is half of the width of the confidence interval, which is half of 0.044, so e = 0.022.

Therefore, the confidence interval 0.252 ± 0.044 can be expressed as:

p - e = 0.252 - 0.022

So, the confidence interval can be written as 0.230 ≤ p ≤ 0.274, where p represents the true value within the confidence interval.

In statistics, a confidence interval is a range of values that is likely to contain the true value of a population parameter. The confidence interval is usually represented as a point estimate (the center point) plus or minus a margin of error.

In the given case, the confidence interval is 0.252 ± 0.044. The center point, denoted as "p," is the estimated value based on the sample data, which is 0.252. The margin of error, denoted as "e," represents the uncertainty or variability in the estimate, which is 0.044.

Expressing the confidence interval in the form of p - e, we subtract the margin of error from the center point to obtain the lower bound, and add the margin of error to the center point to obtain the upper bound. In this case, the lower bound is 0.252 - 0.022 = 0.230, and the upper bound is 0.252 + 0.022 = 0.274.

So, the confidence interval 0.252 ± 0.044 can be interpreted as stating that we are 95% confident that the true value (represented by p) falls within the range of 0.230 to 0.274. This means that if we were to repeat the sampling process and construct confidence intervals in the same way, approximately 95% of those intervals would contain the true population parameter.

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. 34 animals because of 34 heads.

94 legs: 4 per cow, 2 per chicken

x= # of cows

y= # of chickens

so x+y=34

4x+2y=94

Multiply the first equation by -2 is -2x-2y=-68 and add it to the first equation.

which is 2x=26. so x=13. Since x+y=34, 13+y=34.

Therefore, y=21

13 cows and 21 chickens.

2. lets say

pizza=y

soda=x

6x+x=14 combine like terms

7x=14 divide both sides by 7

x=2

So a soda is $2.

6*2=12. So the pizza is $12.

12+2=14. So it's correct.

3.

# of DVDS=x

# of Bluray= y

11x+17y=95

x+y=7

Solution

Correct option is C

It will take 12 seconds until Hudson and Knox have run the same number of feet.

Let's denote the time it takes until Hudson and Knox have run the same number of feet as "t" (in seconds).

The distance Hudson runs can be calculated by multiplying his speed (8.8 feet/second) by the time "t". Thus, the distance Hudson covers is 8.8t feet.

Knox, on the other hand, had a head start of 30 feet. So the distance Knox covers can be calculated by multiplying his speed (6.3 feet/second) by the time "t" and adding the head start of 30 feet. Thus, the distance Knox covers is 6.3t + 30 feet.

To find the time when both runners have covered the same distance, we set their distances equal to each other:

8.8t = 6.3t + 30

Simplifying the equation:

2.5t = 30

Dividing both sides by 2.5:

t = 30 / 2.5

t = 12

Therefore, it will take 12 seconds until Hudson and Knox have run the same number of feet.

Question: In a sale, the price of a book is reduced by 25%. The price of the book in the sale is £12. Work out the original price of the book

Answer: £16

Step-by-step explanation:

To determine the original price of the book, we can use the fact that the sale price is 75% (100% - 25%) of the original price. Let's denote the original price as x.

75% of x = £12

To solve for x, we can set up the equation:

0.75x = £12

To isolate x, we divide both sides of the equation by 0.75:

x = £12 / 0.75

x = £16

Therefore, the original price of the book was £16.

The equation of the circle centered at the origin with a radius of 12 is x² + y² = 144.

In order to find the equation of a circle centered at the origin with a radius of 12, we need to use the standard form equation of a circle, which is:

(x - h)² + (y - k)² = r²

Where (h,k) represents the center of the circle, and r represents the radius.

In this case, since the circle is centered at the origin, h = 0 and k = 0. Also, since the radius is 12, we can substitute r = 12 in the above equation to get:

x² + y² = 12²

Simplifying further, we get:
