I believe the answer is acute. Hope this helps!!
Hi there! The answer is 56 + 8x square feet
The length of a rectangle is 8 feet.
The width of that rectangle is 7 + x feet.
We can find the area of the rectangle by using the formula A = L x W
(Area = Length x Width)
Filling in this formula gives us:
A = 8 (7 + x) = 56 + 8x square feet
Y=mx+b
y=(1200-2x)/3
y=1200/3-2/3x
y=400-2/3x
y=-2/3x+400
U want to go x2 plus x so its x3 then 4x3times -15 so x=3.33333
