The surface area of this three-dimensional figure is equal to 536.6 square centimeters.

<h3>How to determine the surface area?</h3>

First of all, we would determine the total area of the three rectangles by using this formula:

Total area = 3 × Length × Width

Total area = 3 × 15 × 10

Total area = 450 cm².

Next, we would determine the total area of the two triangles by using this formula:

Total area = 2 × (1/2 × b × h)

Total area = b × h

Total area = 8.66 × 10

Total area = 86.6 cm².

Surface area = 450 + 86.6

Surface area = 536.6 cm².

Solving a polynomial inequation

Solving the following inequation:

(x - 8) (x + 1) > 0

We are going to find the sign both parts of the multiplication,

(x - 8) and (x + 1), have when

x < - 8

-8 < x < 1

1 < x

Then we know (x - 8) (x + 1) > 0 whenever (x - 8) (x + 1) is positive

We can see in the figure (x - 8) (x + 1) is positive when x < -8 and x > 1

Then
