$since \: they \: are \: similar \\ \frac{x + 2}{32} = \frac{3}{12} \\ crossmultiplying \\ 32 \times 3 = 12(x + 2) \\ 96= 12x + 24 \\ 12x = 96 - 24 \\ 12x = 72 \\ dividing \: bothsides \: y \: 12 \\ x = \frac{72}{12} \\ x = 6$

(2a^x +1/2 b^x)^2 thank you!!!!!!!!!!!!!!!!!!!1

Note that (a+b)^2 = a^2 + 2ab + b^2.

Therefore,
b^x (b^x )^2
(2a^x +1/2 b^x)^2 becomes (2a^x)^2 + 2(2a^x)(-------- ) + ------------
2 4

LCD is 4. Thus, we have

4 [ (2a^(2x) ] + 8a^x*b^x + b^(2x)
