1. The face of a lamp shade is shaped like a trapezoid. The dimensions of the face are shown in the diagram. 6 in. A = 5(6+10)y y in. xin. y in. A = 5(6 + 10) 6 x 10 in. Which equabon can be used to find A, the area of the face of the lamp shade in square inches? O 1 = {(6) + (10)x A= = {(6) + (10) CLEAR ALL Oz 03 04 OS O 6. 07 08 9 e O 10

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

it is a horizontal line.
