PLEASE HELPP AND EXPLAIN!!

5x + 18

Step-by-step explanation:

This question is very strange, in that, you aren't finding x or how long the sides are. The "missing" side in the directions is the unmarked side.

If you add up all four sides that are labelled you find the x terms add up to 20x, but it is given that the Perimeter is 25x + 8. So the x part of the unmarked side must be 5x.

Then you'll see if you add up all the plain numbers (constants) they add up to -10. But again they told us that the perimeter is 25x + 8. So the constants need to add up to 8. We have to makeup the -10 and also 8 more for a total of 18.

The unlabelled side must be 5x + 18.

Confirm, all the sides added up, Perimeter=

(5x+18)+(4x)+(5x+2)+(5x-4)+(6x-8)

=25x+8

x + 107

step-by-step explanation:

let's say that the number he had before the mistake was x. then, he will have 107 dollars more than this, so the answer is x + 107.
