The correct answer is 179. I will explain the steps I took to find the correct answer.

First write the problem- 5x^2+x-7, also be reminded x=6.

Second lets begin to start solving it.

6 squares equals 36 ( also known as 6×6)

Now 36*5=180. This is the first half of the problem.

Continuing to solve

180+x-7

Remember x=6 so now 180+6-7

Finally you find your answer by solving 180+-1, which is 179

First, substitute 6 in for x:
5 x 6^2 + 6 - 7
Simplify:
30^2 + 6 - 7
30^2 + 1
900 + 1
901

Hope this helps!!
