Bill and Ron build towers using blocks. The expression 4b + 2 represents the number of blocks Bill uses. The expression 8b – 5 represents the number of blocks Ron uses.

Complete the expression to represent the total number of blocks Bill and Ron use.

Answer 1

`4b+2-Bill's\ blocks\\8b-5-Ron's\ blocks\\\\4b+2+8b-5=\\12b-3\\\\Total\ number\ of\ blocks\ is\ 12b-3`

Answer 2

Bill = 4b + 2.
Ron = 8b - 5.

Bill + Ron = (4b + 2) + (8b - 5).
= 4b + 8b + 2 - 5.
= 12b - 3.

That's the expression for the total number of blocks used by both Bill and Ron.
