Question

Let x = 6. What is the value of the expression 5x to the 2nd power +x−7 ?

Answer 1

149

Explanation:

5 to the second power is 25, because you do 5x5. Then you multiply 25 by x, which is 6, and get 150. Then you add 6 to 150, which is 156, and subtract seven. Also the answer is 149.

Answer 2

The answer is 149

Explanation:

The equation is

5x² + X -7

Putting X as 6 we get

=5(6)²+6−7

=(5)(36)+6−7

=180+6−7

=186−7

=179
