Every square root has the same radicand, which is 10. So, simply combine terms.

7 + 2 - 1 = 9 - 1 = 8

Answer: 8√10

Answer: 18 days

Step-by-step explanation:

10 + 3x = 4x - 8

you see this? pretty cool setup here

ok

so now lets combine like terms. do the opposite on both sides. whats the opposite of 4x? -4x so lets subtract 4x from both sides

10-x=-8

ok now add 8 to both sides

18 - x = 0

x = 18

OH YEAH!!!! YOU GOT THIS!!!! MASTER OF MATH!!!! OH YEAH!!!! CURIOSITY!!!!!!!!!!!

Answer:

First is equivalent then 29 last equivalent

Step-by-step explanation:

If both expressions have the same value,  then they are equal to each other.

The equivalent is the expressions that are in different forms but are equal to the same value.

Consider the expressions 5 + 8k and 8k + 5.

Using k = 3

 5 + 8k = 8k + 5

5 + 8(3) = 8(3) + 5

5 + 24 = 24 + 5

     29 = 29

Using k = 5

 5 + 8k = 8k + 5

5 + 8(5) = 8(5) + 5

 5 + 40 = 40 + 5

        45 = 45

If both expressions have the same value after substituting and simplifying two different values for the variable, then they are equal to each other.

Answer:

Step-by-step explanation:

The formula for the volume of a rectangular prism is V = lwh, where V is the volume, l is the length, w is the width, and h is the height.

We know that V = 5,890.625 cm^3, h = 14.5 cm, and l = 25 cm.

Substituting these values into the formula, we get:

5,890.625 = 25w(14.5)

5,890.625 = 362.5w

w = 16.25

Therefore, the width of the rectangular prism is 16.25 cm.

Answer:

It's A

Step-by-step explanation:
well all you have to do is divide like 5,890.625 dvided by 14.5 then divide again by 25 them bam you got 16.25

The point at (-3, 4) is at a distance of 5 units from the point (0, 0).

For two points (x₁, y₁) and (x₂, y₂), the distance between them is given by the formula:

distance = √( (x₁ - x₂)² + (y₁ - y₂)²)

In this case, we want to get the distance between (-3, 4) and (0, 0), using the above formula we will see that the distance is:

distance = √( (-3 - 0)² + (4 - 0)²) = √25 = 5

The distance is 5 units.

To find the equation of a parabola, we can use the formula f(x) = ax^2 + bx + c, where a, b and c are congruent vertices.

Alternatively, we can use PF = PM to find the equation of the parabola.

vertex is half way between the focus and directrix

It's a downward opening parabola, general form

5.5km/hr is the speed at which he walks.

Two or more expressions with an Equal sign is called as Equation.

Given

w = walking speed

t = time walking = 2

Given, A man walks for 2 hours at a certain speed which is 2w

He then cycles at three times that seed for 4 hours.

We can form a equation by given data

2w + 3×w×4 = 77

2w+12w=77

14w = 77

Divide both sides by 14

w = 5.5 km/hr

Answer:

Step-by-step explanation:

From the question, a water glass can hold 2/9 of a litre of water, to know the number of glasses of water that can be filled with a 3-litres bottle, the following steps are crucial;

1 water of glass = 2/9 litre of water

x = 3 litre of water

cross multiplying;

2/9 * x = 3*1

2x/9 = 3

2x = 27

Dividing both sides by 2;

2x/2 = 27/2

x = 13 1/2

This means 13 1/2 glasses of water can be filled with a 3-litre bottle.

The quotient of the given expression is 68.

What is the quotient?

A quotient in mathematics is the amount created by dividing two numbers. The term "quotient" is used frequently in mathematics and is sometimes known as the integer portion of a division, a fraction, or a ratio.

For the given problem,

To find out the estimation of the quotient, we first round the dividend and the divisor to the closest tens, hundreds, or thousands, and then divide the rounded figures to approximate the quotient.

Given, 3411 divided by 53

So, the rounding value becomes 3400 divided by 50,

then, 3400/50 = 68

Hence, the quotient is 68.

So I know the \(\sqrt{4}\)=2 so i can take both out so outside the root will be 2*2 and inside the root will be 3

Now for the b's for every pair there are, you can take that out.  There are 3 pairs of b's so b³ is outside and one b is left inside.
