6m + 5 - 3m = 7 (m-1)
6m + 2m = 7m - 7
8m = 7m - 7
m = -7
Answer:B
Step-by-step explanation:
Given that square print has side length = 8 inches
Given that you make a frame using strip of wood 1 1/4 inch wide. Since frame is on both sides of the square print so new side length after adding the frame =
inches
Area of the square is given by formula
where x is the side of square
Shape of the frame including print will also be square so
Area of the frame including print
square inches
Area of the print =
square inches
We have to find the area of frame only so we can subtract area of print from the total area
Area of frame = [Area of frame including print] - [Area of print]
Area of frame = 110.25-64 = 46.25
Hence final answer is 46.25 square inches
