Answer:
16
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
y(y² + 4y + 16) - 4x(y² + 4y + 16) ← distribute both parenthesis
= y³ + 4y² + 16y - 4xy² - 16xy - 64x
Compare - axy to - 16xy ⇒ a = 16
First error is that the legs are a and b so a should be x and b is 6 and c is 10 the second error is at the end they did not take the square root to get x by itself the real answer should be
X^2 +6^2=10^2
X^2+36=100
X^2 =64
X=8
The answer is B. x > -22
-5x + 20 < 130
-5x < 130 - 20
-5x < 110
-5x/-5 > 110/-5
x > -22
