The length of a rectangle is six times its width.
if the area of the rectangle is 600yd^2, find its perimeter.

If a =6, what is the value of 2a(3b + 5c)?

Ireally need subtract and simplify.(-y^2 – 4y - 8) – (-4y^2 – 6y + 3)show your work, ! i will mark you brainliest but you have to show your work.
