Solve for x:
(-4 x - 2) (x - 7) = 0
Split into two equations:
-4 x - 2 = 0 or x - 7 = 0
Factor constant terms from the left hand side:
-2 (2 x + 1) = 0 or x - 7 = 0
Divide both sides by -2:
2 x + 1 = 0 or x - 7 = 0
Subtract 1 from both sides:
2 x = -1 or x - 7 = 0
Divide both sides by 2:
x = -1/2 or x - 7 = 0
Add 7 to both sides:
Answer: x = -1/2 or x = 7

I'm not sure but I think so
To find the unit rate, you would have to divide $10.75 by 3, which equals $3.58. The unit rate would be $3.58 per pound.

Answer:
3.15 ft
Step-by-step explanation:
V
<em>Volume of a cylinder: πr²h</em>. Solving for r², we get r² = ---------
πh
Here, we get r² = (117.1 ft³) / (3.14·15 ft) = 2.48 ft² and r = √(2.48 ft²), or
1.58 ft, so that the diameter is 2r, or 3.15 ft
The diameter of the base of the cylinder is 3.15 ft.
