Answer:
4+3x
Step-by-step explanation:
-2x and 5x could be combined since they're like terms
Instead of 4-2x+5x, the expression would be 4+3x.
As h increases 80/h decreases . When h approaches infinity 80/h approaches zero.
We can do several rectangles and 2 triangles
the easiest way is to find the area of the big rectangle minus the cut off pices
a. 1 big rectangle-2 corner triangles
b. area rectangle=lenght times height=24 times 11=264 square feet
the triangles
bottom left one is height 11-7=4 and base 24-14=10
bottom left=1/2 times 4 times 10=20
top right is 24-20 by 11-6 or 4 by 5, area=1/2 times 4 times 5=10
so
rectangle-triangles=264-(20+10)=264-30=234 square feet
7x=42
Divide 42 by 7
X=6
