Answer:

x = -4 is not the solution to the equation because when you see the sign ≤ means there would be many numbers, can't count all of them but the answer would not be any specific number!

Hope this helped :3

Answer:

Step-by-step explanation:

To determine if x = - 4 is a solution to the inequality, substitute x = - 4 into the left side of the inequality and compare with right side.

5(- 4)² + 10(- 4) - 25

= (5 × 16) - 40 - 25 = 80 - 40 - 25 = 15 > 10

Since left side > right side then x = - 4 is not a solution
