The easiest thing to do here is to split into two right triangles. The split will occur at x=1.
A= (base times height) / 2
Height of both is 3
Base of left is 6
Base of right is 3
(6*3)/2 = 9
(3*3)/2 = 4.5
Now, add together.
9 + 4.5 = 13.5 sq units
The answer is $337.50 paid. We would change 7 1/2% (7.5%) to its decimal form which is .075. Then we would multiply that by $4,500 which would get $337.5 or $337.50 which is the same thing. Hope this helped!
L think that the answer is A-Rises Falls
3/2 is the slope. 3/2x to be precise
Answer is a sphere (ball shape)
