Need to know the area of the composite figure.

  52.5 cm^2

Step-by-step explanation:

The base length of the triangle on top is ...

  8 cm - 1 cm - 2 cm = 5 cm

Then the area of that triangle is given by the formula ...

  A = (1/2)bh = (1/2)(5 cm)(5 cm) = 12.5 cm^2

___

The area of the rectangle below that triangle is the product of its length and width:

  A = (8 cm)(5 cm) = 40 cm^2

___

The total area is the sum of the areas of the rectangle and triangle, so is ...

  total area = 40 cm^2 + 12.5 cm^2 = 52.5 cm^2

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
