A window is constructed in the shape of a trapezoid as shown on the side of a building. If all angles that appear to be right angles are right angles, find the area of the window.
A) 450 square feet
B) 480 square feet
C) 500 square feet
D) 520 square feet

This is a trapezoid.

Area=(20+(20+6+6))×20/2=(20+32)×10=52×10=520 square feet

D)

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
