${a}^{ - m} = \frac{1}{ {a}^{m} }$

$(a {}^{m} ) {}^{n} = {a}^{ mn}$

${a}^{m} \times {a}^{n} = {a}^{m + n}$

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.
