Find the area.

211 cm

Step-by-step explanation:

upper  rectangle + lower rectangle (11-8=3) + end triangles

(8x20)                  + (3x12)                              + (1/2x3x5 each  x2)

160+36+15=211

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

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
