Which expression can be used to find the area of the composite figure? a. 4xb. 2x+2x^2c. x^2+2xd. 3x^2the answer is 3x^2

The Correct Answer is 3x2

The correct option is D.

Step-by-step explanation:

The given figure contains two congruent triangle and one rectangle. The length of the rectangle is 2x and width of the rectangle is x. The height and base of the triangle is same, i.e. x.

The area of rectangle is

The area of triangle is

The area of given figure is

Total Area = Area of rectangle + 2(Area of a triangle)

The area of given figure is , therefore the correct option is D.

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

it is b)

hope this : )
