To find the surface area of the given figure identify all the faces on the figure, calculate the area of each face and then sum the areas:
Measures in red
Number of faces in green, total faces 9
Area of a triangle:

Area of a rectangle:

Area of faces 1 and 2(rectangles):

Area of faces 3 and 4 (triangles):

Area of faces 5 and 6 (rectangles):

Area of faces 7 and 8 (rectangles):

Are of face 9 (rectangle):

Total surface area:

<h2>Then, the surface area of the given figure is 1108 square inches</h2>
Answer:
<h2>12(x - 2) - 8x + 3 = 4x - 21</h2>
Step-by-step explanation:

Answer:
Answer B:
times
Step-by-step explanation:
To find how many times more massive is the whale relative o the polar bear, we just need to find the quotient of one over the other:
times
Therefore our answer agrees with the one shown as answer B.
Answer:
After 9 years, the population reach 4000.
Step-by-step explanation:
The given function P(t) represents the size of a small herbivore population at time t (in years).

We need to find the number of years after which population reach 4000.
Substitute P(t)=4000 in the above function.

Divide both sides by 1000.

Taking ln on both sides.

![[\because \ln e^x=x]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cln%20e%5Ex%3Dx%5D)
Divide both sides by 0.16.


We need to find the number of years. So, round the answer to the next whole number.

Therefore, after 9 years, the population reach 4000.
