Answer this please (9)

The answer is C 10.

Step-by-step explanation:

Since there is a parentheses around 2⁴, we know that we are multiplying the exponent in  (2⁴) by 3. This will give us a product of 2¹².

Since 2¹² is set equal to 2² x 2^n, we know that whatever n equals will be added to the exponent of 2 to get 12.

We know this because since there are no parentheses, when we see the x (multiplication sign) we know that we are adding and not multiplying.

2^12 - 2² = 2¹⁰. So our answer is C. 10

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
