Answer:

The expression that can be used to represent the volume of the trapezoidal prism is  (2x^3+6x^2)

Step-by-step explanation:

step 1

Find the area of the trapezoidal base

The area of a trapezoid is given by the formula

A=\frac{1}{2}(b_1+b_2)h

we have

b_1=(x+2)\ units\\b_2=(x+4)\\h=x

substitute

A=\frac{1}{2}(x+2+x+4)x

A=\frac{1}{2}(2x+6)x

A=(x+3)x\\A=(x^2+3x)\ units^2

step 2

Find the volume of the trapezoidal prism

we know that

The volume of the prim is given by

V=Bh

where

B is the area of the base

H is the height of the prism

we have

B=(x^2+3x)\ units^2

H=2x\ units

substitute

V=(x^2+3x)2x\\V=(2x^3+6x^2)\ units^3

therefore

The expression that can be used to represent the volume of the trapezoidal prism is

(2x^3+6x^2)

Can someone please help me with this? It’s the last problem I need to turn in a test, I will mark brainliest :(

Answer:

33b - 8

Step-by-step explanation:

You solve for the perimeter like you would for any other shape by adding all the sides

The perimeter is side A + side B + side C.

so it's 9b+8 + 12b-8 + 12b-8

Add all the like terms

9b + 12 b + 12b = 33b

8 - 8 - 8= -8

= 33b -8

Identify all polar coordinates of (2, 0°). Please include all steps. Thanks.
Alekssandra [29.7K]

(2, 0°) is already in polar coordinates, with the smallest possible angle. The radius is 2, always 2. Expressions with variations of the angle are also good representations of (2, 0°) if their angles are all integer multiples of 360 degrees. For example: (2, 720°) represents the same point in polar coordinates as does (2, 0°).
