Hello!

First:

write an equation.

5x + (7x+8) + (7x+2) = 143

now combine like terms

19x + 10 =143

now subtract 10 from both sides

19x = 133

divide 19 on both sides.

x = 7.

Are you done here? Nope, we need to find out what each side is, so lets plug in the number 7 for x.

-----------------------------

For the side 5(x)

5(7) = 35

This side is 35m

-----------------------

For the side 7x + 2

7(7) + 2

49 + 2

This side is 51m

------------------------

For the side 7x + 8

7(7) + 8

49 + 8

This side is 57m.

------------------------

I hope this helps,

Have a great day!

Answer:

The correct answer is letter "C": what-if analysis.

Explanation:

A what-if analysis is a study an individual or company makes about a certain number of events where variables are changed to determine what the outputs would be. This approach is normally implemented when there is limited information from where to make a concise decision. Then, individuals have to outline all the possible results to find out what their risks are.

Software like Microsoft Office Excel facilitates the implementation of what-if analysis.
