Let the length equal x
Then the width would be 4x + 8 (8 feet more than 4 times the length)
Area = length x width:
5,472 = x * 4x+ 8
Simplify:
5472 = 4x^2 + 8x
Subtract 5472 from both sides:
4 x^2 + 8x - 5472 = 0
Use the quadratic formula to solve for x.
X = 36
Now you know the length is 36 feet
The width = 4(36) + 8 = 152 feet
Now find the perimeter: 152 + 152 + 36 + 36 = 376 feet.
The answer is B. 376
Work = force * distance
1800 ft-lb = force * 15 ft
force = 1800 ft-lb / 15 ft
= 1800/15 ft-lb/ft
= 120 lbs

Answer:
x = 25/9 or 2.777777778
Step-by-step explanation:
4(2-x) = 5x - 17
8 - 4x = 5x - 17
<u> +4x +4x</u>
8 = 9x - 17
<u>+17 +17</u>
25 = 9x
25/9 = x
x = 2.777777778 or 25/9
