What is the length of the hypotenuse?​

The answer is c = 17 feet

Step-by-step explanation:

The formula to find the hypotenuse is a^2 + b^2 = c^2 (a squared plus b squared equals c squared).  

a = 8 feet

b = 15 feet

a^2 = 8 * 8 = 64

b^2 = 15 * 15 = 225

The next step is to add: 64 + 225 = 289

But we need to remember to square root 289 because we squared a and b.

The square root of 289 equals 17

c = 17 feet

step-by-step explanation:

subtract 7, so the answer is x < = 3, or c.

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
