Answer:
D
Step-by-step explanation:
The factored from of a polynomial can be found from the zeros or x-intercepts of the graph.
The x-intercepts here are x= -3 and x= 3.
Then the factors are x+3 and x-3.
So the factored form is (x+3)(x-3).
Answer:
180 ft2
Step-by-step explanation:
First solve for the area of the trapzeoid using formula:
A= a+b/2xh
10+18x6/2
A= 84 ft2
Then solve for the rectangles B and C:
12x4= 48
48x2 (because theres two rectangles) which equals 96
Combine the two to get the total area:
96+84= 180
We will use integration by substitution, as well as the integrals

Final answer
No thank you IoI, good luck tho <3
Answer:
Step-by-step explanation:
a) y=
x=-1 ⇒ y=
x=1 ⇒ y=
x=2 ⇒ y=
x=4 ⇒ y=
b) =
so the blue one
