If 3 to the power of k+3 minus 3 to the power of k equals m, what is 3 to the power of k+2 in terms of m?

3^(k+2) = 9m/ 26

Step-by-step explanation:

Let 3^k = y :

y×3^3-y = m

26y = m

26×3^k = m

3^(k+2) = m/26×3^2

Therefore 3^(k+2) = 9m/26

i think the answer is b.

step-by-step explanation:

not 100% sure though.
