Which statement comparing x² + 10 and x + x + x is true when x=−5 ? a. x2+10 b. x² + 10 = x + x + x c. x2+10> x+x+x

X^2 + 10 = 35 when x = -5
x + x + x = 3x = -15 when x = -5.

The answer is B because part A just restates the first equation, and Part C determines which is greater. If you want to determine the difference between the two when x = -5, part B is the best answer because it subtracts the product of one of them from the other.
