Bailey writes the expression g2 + 14g + 40 to represent the area of a planned school garden in square feet. If g = 5, what are t
ikadub [295]
The expression is A=g^2 + 14g + 40.
D=14^2-4\cdot 40=196-160=36 \\  \sqrt{D}=6  \\ q_{1,2}= \dfrac{-14\pm 6}{2}  =-4,-10.
Then A=g^2 + 14g + 40=(g+4)(g+10).
The width is g+4, the length is g+10.
When g=5, 
g+4=9 ft and g+10=15 ft.
Answer: correct choice is D.
