A wheelbarrow is being used to carry wet concrete. Here are its dimensions. 1.) What volume of concrete would it take to fill the tray.
2.) After dumping the wet concrete, you notice that a thin film is left on the inside of the
tray. What is the area of the concrete coating the tray? (Remember, there is no
top.)

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.
