Please help!
Really confused!

For number 15.) the area of the circle is 1,017.4

Step-by-step explanation:

To find the area of a circle using the radius the equation has to be

3.14 x Radius to the power of 2

so in this case it was 18 x 18=324

Then you multiple 324 with pie which is 3.14

324x3.14=1,017.4 rounded to the tenth

I hope this helps :))

use khan academy too their videos help a lot for me :)

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

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
