Answer:
5391.76
Step-by-step explanation:
We have a rectangle and 2 semicircles
First find the area of the rectangle
A = l*w
A = 44*88= 3872
Then we know that 2 semicircles = 1 circle
The area of a circle is
A = pi r^2
The diameter is 44 so the radius is 22
A = pi * 22^2
A = pi484
A =1519.76
Add the areas together
1519.76+3872
5391.76
8x^2+10x-18

I believe it’s expression c sorry if I’m incorrect
Answer:
d=3 and e=-1
Step-by-step explanation:
d+e=2
d=2-e-----(1)
d-e=4-----(2)
substituting (1) in (2)
2-e-e=4
-2e=2
e=-1-----(3)
substituting (3) in (1)
d=2-(-1)
d=3
