Question

Melvin is building a castle with a series of towers out of blocks. Each tower has twice as many blocks as the previous tower, and then 3 more. If the first tower has x^2+2x+3 blocks in it, and Melvin builds 5 towers in all, how many blocks will he have used in total?

Welcome !

Answer 10

@sirizarry78 sry made a mistake before. It's gonna be 2(x^2+2x+3)+3 for the 2nd tower
and 2[ 2(x^2+2x+3)+3]+3 for the 3rd tower....
Number of blocks used for the 5th will look like :
2(2( 2[ 2(x^2+2x+3)+3]+3)+3)+3
You won't have to simplify all that if you see that the factor of x^2 is 2*2*2*2=16
