Answer:
226 11/20 cm^2.
Step-by-step explanation:
This consists of 2 trapezoids and 4 rectangles.
Area of the 2 trapezoids = 2 * 4 *(6 1/2 + 5 1/4 ) /2
= 47 cm^2.
Area of the 4 rectangles = 4*9 + 6 1/2 * 9 + 4 1/5 * 9 + 9* 5 1/4
= 36 + 117/2 + 189/5 + 189/4
= 3591/20 cm^2
Total surface area = 47 + 3591/20
= 4531/20
= 226 11/20 cm^2.
He has 16 choices, because 5+3 is 8, times two would be 16

Answer:
= x^4 -x^3 -4x^2 -3
Step-by-step explanation:
f(x) = x^4 -x^2 +9
g(x) = x^3 +3x^2 +12
We want to find f-g
(f-g) (x) = x^4 -x^2 +9 - (x^3 +3x^2 +12)
Distribute the minus sign
(f-g) (x) = x^4 -x^2 +9 - x^3 -3x^2 -12
= x^4 -x^3 -4x^2 -3
30 for the first and 83.5 for the second
