Me find the answer and explain the process to find the answer of the problem appreciate it : )

x = 5

Step-by-step explanation:

Pythagorean Theorem

side a = x

side b = x + 7

side c = x + 8

therefore:

This would result in:

Let's combine our like terms:

This looks like a mess, but now we need to take all the value from the right side and move them to the left side using inverse operations. This would result in:

Again, combine like terms:

Now we factor:

(x-5)(x+3) = 0

Solving gives us:

x - 5 = 0 or x = 5 and x+3 = 0 or x = -3

Since we cannot have a negative distance we can discard the -3.

We plug in the 5 for X making the following:

Side a = 5

Side b = 12

Side c = 13

Check our Work

25 + 144 = 169

169 = 169 is true so x is indeed 5.

Whew!

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
