Will mark brainleist give me a good summary of the pythagorean theorem

Pythagorean Theorem = a^2 + b^2 = c^2

This is used to solve the hypotenuse of the triangle (the unmarked horizontal side). It takes the sides, which are a and b, and puts them to the power of 2. After that, you take the number, for example lets say 16. You'd find the square root, and that'd be your anwser, (for this example the anwser would be 6).

another example:

side one of triangle (A) (length) = 6

side two of triangle (B) (width) = 8

hypotenuse (C) = ?

(6)^2 + (8)^2 = 36 + 64 = 100. The square root of 100 is 10. C is 10.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
