Hi, I'd be glad to help with this equation. 

Answer is (A. 9d+5) 

The reason is if d=4 the 9 ^ (d=4) then replace d with 4 so (9 ^ 4) = 36 

then add your 5 to the equation (36 + 5) = 41 

So, (A) is equal to 41 

Hope this helps. 
Have a great day!

Substitute in the value of d in all expressions to solve:

A. 9(4) + 5 = 41
B. 7 + 3(4)² = 55
C. 10(4) - 1 = 39
D. 11(4) - 12/4 = 41
E. 4³ - 2³ = 56

Expressions A and D are equal to 41 when evaluated that d=4.

Hope this helps :)
