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.

I need help. What are the two numbers on the middle
Rina8888 [55]

Answer:

  Miles: 35; Gallons: 1

Step-by-step explanation:

The number of gallons can be any number of your choosing that is less than 12, which is the capacity of the tank. For the purpose here, 1 is a convenient number. To find the corresponding number of miles (m), you need to solve the proportion ...

  420/12 = m/1

  35 = m

  (miles, gallons) = (35, 1) . . . a suitable choice for the table values

__

<em>Additional comment</em>

If your sense of symmetry is offended by choosing 1 for Gallons, you can choose 10, a number halfway between 12 and 8. In that case, your proportion is ...

  420/12 = m/10   ⇒   m = 350

Then, your entry would be ...

 (miles, gallons) = (350, 10)
