Remaining feet of board is found by finding the difference between total length of board and foot that was cut off

Substituting the values we get,

Thus
feet board is left
New amount = starting value x (1- percent)
New amount = 250 x (1-0.34)
New amount = 250 x 0.66
New amount = 165

13) 14(5x + 2)(3x - 1)
14) (4h - 1) and (h + 6)
15) 3 and (a - 2) and (a + 8)
16) 5 and (4w - 1) and (w + 2)
Answer:
looks like 9.5, but kinda hard to tell
