Answer:
Probably A?
Step-by-step explanation:
X=-6
You get all the X to one side, and all the numbers to the other. Then divide. Work is shown in image below.
Area of Frame and Picture
Area = L * W
L = 9
W = 6
Area = 9*6 = 54 in²
Area of Picture
Area = L*W
L = 6
W = 4
Area = 6 * 4
Area = 24 in²
Area of Frame
Area of Frame = Total Area - Picture Area
Area of Frame = 54 - 24
Area of Frame = 30 in²
