Answer:

10x + 4

Step-by-step explanation:

Combine like terms.

First combine the numbers that have the letter x:

  • <u>-3x</u> <u>+ 8x</u> + 2 <u>- 3x</u> <u>+ 8x</u> + 2
  • <u>-3x + 8x -3x +8x</u> + 2 + 2
  • <u>10x</u> + 2 + 2

Then combine the ones that don't have the letter x

  • 10x <u>+ 2</u> <u>+ 2</u>
  • 10x + 4

Answer is 10x+4

How do you create a restriction for √z + 8=13 ?
Zinaida [17]
√z = 13 - 8
√z = 5
z = 5²
z = 25
In this case the z can be any number, however z cannot be less than 0 and that is the restriction. (for example; √-1 = irrational number, cannot be solved.)

The height in feet is modelled by the function below, where the t is in
Sedaia [141]

The object reaches the lowest height at 5 seconds

<h3>How to determine the time?</h3>

The function is given as:

f(t) = -2t² +22t + 6

Differentiate the function

f'(t) = -4t +22

Set to 0

-4t +22 = 0

Subtract 22 from both sides

-4t = -22

Divide both sides by -4

t = 5.5


Remove decimal points

t = 5

Hence, the object reaches the lowest height at 5 seconds

Answer:

V≈653

Step-by-step explanation:

In order to find the volume of a cylinder, you use the formula V=πr2h. In this case, the filled-in formula would be V=3.14*4*4*13. This equals 653.45. In your answer, you need to round to the nearest whole number. In this case, round down to 653. That is your answer. Hope this helps :)
