HG^2 = FG * (FG + EF)
Fill in the values:
(x+3)^2 = x * (7+x)
Simplify the right side:
(x+3)^2 = 7x +x^2
Rewrite the left side using the FOIL method
x^2 + 6x + 9 = 7x +x^2
Subtract x^2 from both sides:
6x +9 = 7x
Subtract 6x from both sides:
x = 9
Now you have x solve for HG
HG = x +3 = 9+3 = 12
The answer is A.

Answer:
10 feet
Step-by-step explanation:
- Multiply 20 by 6 which will give the answer 120 (in inches).
- Then convert 120(inches) to feet by dividing with 12.
- The answer will be 10(feet) needed for six shelves.
20x6= 120
120/12=10
=10 ft
