Answer: -8
Here’s why: you start by subtracting the 4 from both sides. Leaving you with
-7y= 56
Divide by -7 on both sides
-7y/-7 = y 56/-7=-8

Answer:

Step-by-step explanation:
Pythagorean Theorem:

where a and b = legs and c = hypotenuse
we are given a leg and the hypotenuse so we plug in what we have into the formula
now we solve for b
step 1 subtract 20^2 from each side

finally we want to get rid of the exponent on the b
to do so we take the square root of each side

we're left with b = 21
Note: They Pythagorean theorem only works with right triangles
