Answer:
8x + 24
Step-by-step explanation:
Given photograph length L = 7" and width W = 5"
Also that the frame is 2x" longer and 2x" wider
hence,
new length = ( 7 + 2x) inches
new width= ( 5 + 2x) inches
Hence perimeter of frame,
= 2 x ( new length + new width)
= 2 [( 7 + 2x) + ( 5 + 2x)]
= 2 (4x + 12)
= 8x + 24 (Answer)
