Hello!
-----------------------------------------------------------------------------------------------------
Part 1
6(2x + 5y)
Distribute the 6
12x + 30y
The answer is 12x + 30y
-----------------------------------------------------------------------------------------------------
Part 2
We put 3 in for x and 4 in for y
12(3) + 30(4)
Multiply
36 + 120 = 156
The answer is 156 square feet
Hope this helps!
