Question

Which of the following are equivalent to 9h+9(2h)? h(9+18) or 9h+17h

Answer 1

we have to first distribute the 9 inside of the parentheses
so 9×2h=18h
So the equation in 18h+9h

if we look at the first equations, h(9+18) and distribute the h then the equation becomes
9h+18h

so h(9+18) is equivalent to
9h+9(2h)
