Answer:
1st pic:
step 2.
2nd pic:
Rene should add, not multiply 2 volumes.
The correct answer is 48+216 =264
3rd pic:
a, for blue prism: V = Area of base x Height = 48 x a =720
=> a = 720/48 = 15
b, for orange prism: V = Area of base x Height = (12xb)/2 x 15 =720
=> b =(720x2)/(15x12)= 8
Area of the big triangle (shaded area and small tris for below) is 36 * 51 divided by 2 (area of triangle is base * height over 2). this would give you 918.
area of the small triangle below is 51 * 11 divided by 2 (see above), which is 280.5.
shaded shape area is the big triangle shape minus the small triangle below, which is 918-270.5, which is 637.5 units.

34.
- h(x) = 8 ⇒
- x = 4 as per diagram
35.
36.
- f(x) = 2 ⇒
- x = -0.8 as per graph (approx.)
37.
38.
- h(-1) = -8 as per diagram
39.
- g(x) = 4 ⇒
- x = 9 or x = 8 as per table
