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!

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
