Answer:

C. 33 square feet.

Step-by-step explanation:

to get the area of irregular polygon.

divide the area into two parts (see attached image)

total area = A1 + A2

where A = 1/2 base x height

total area = ( 1/2 * 6 * 8) + (1/2 * 6 * 3)

total area = 24 + 9

total area = 33 square feet.

therefore the answer is C. 33 square feet.

G(b) = 5b- 9 h(b) = (b - 1)^2 Evaluate. (hog)(-6) =
laiz [17]

Given:

The two functions are:

g(b)=5b-9

h(b)=(b-1)^2

To find:

The value of (h\circ g)(-6).

Solution:

We have,

g(b)=5b-9

h(b)=(b-1)^2

We know that,

(h\circ g)(b)=h(g(b))

(h\circ g)(b)=h(5b-9)

(h\circ g)(b)=[(5b-9)-1]^2

(h\circ g)(b)=[5b-10]^2

Putting b=-6, we get

(h\circ g)(-6)=[5(-6)-10]^2

(h\circ g)(-6)=[-39-10]^2

(h\circ g)(-6)=[-49]^2

(h\circ g)(-6)=2401

Therefore, the value of (h\circ g)(-6) is 2401.
