Ok..
8(5+w)
That would be
8w + 40
First you will have to multiply the 8 to the variables in the parentheses..
So 8 times 5 would be 40 WITHOUT a w because the w is not with the 5
Next the 8 times the w, which would be 8w
(I like to put the smaller number in front of the bigger number, it makes it easier to write that way)
