Answer: Add 2 to each side
Step-by-step explanation:
9m-2=16
+2 +2
9m=18
Factor out the 5. 5(x - 6)
There are 12 such shapes. One can start with two squares, adding squares around the edge and rejecting shapes that have been previously seen. Repeating until you have 5 squares results in 12 distinct shapes.
_____
2 shapes are possible with 3 squares: L, I
5 shapes are possible with 4 squares: L, I, N, T, O
Hyp^2 = 8^2 + 9^2
hyp^2 = 64 + 81
hyp^2 = 145
hot = 12 inch
find the square root of 169
√169 is 13
= 13 feet
