Question

Are the two expression equivalent when x=5

Answer 1

Yes

Explanation:

Substitute 5 into the equation.

9 * (4 * 5 + 2) = 9 * (20 + 2) = 9 *22 = 198

36(5) + 18 = 180 + 18 = 198

The two expressions both equal 198, so yes they are equivalent when x = 5.

Answer 2

They are equivalent

Explanation:

9(4(5)+2)=9(20+2)=9(22)=198

36(5)+18=180+18=198
