Answer:
(x + 10)^2
Step-by-step explanation:
*It helps to draw a diagram for these types of questions
Side length of photograph: x + 8
Width of frame: 2 in.
Area of a square: s^2
A = ((x + 8) + 2)^2
= (x + 10)^2
Therefore the area of the photograph with the frame is (x + 10)^2
Answer:
- 8(x + 10) or 8x + 80
Step-by-step explanation:
Area of the picture:
- (x + 8)²
Side of the photograph with the frame:
- (x + 8) + 2*2 =
- x + 12
Area of the frame:
- (x + 12)² - (x + 8)² =
- (x + 12 + x + 8)(x + 12 - x - 8) =
- (2x + 20)(4) =
- 8(x + 10)
or
- 8x + 80
