Step-by-step explanation:

A

Step-by-step explanation:

First we need to find the perimiter of a parallelogram

Side A is the slanted line,

Side B is the 2 horizontal lines.

The equation for this is 2(a+b)

Let's plug in the measurements:

2(18+27) =

2(45) =

90

So the parallelogram is 90 now we have the perimeter of the semi cirlce already which is 18

90 + 18 = 108

Hope this helps :)

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
