X(x-20)=12000
x^2 - 20x = 12000
x^2 - 20x - 12000 = 0
(x - 120)(x + 100) = 0
x = -100, 120
so the width is 120 ft
The answer is 1.) 6^1/6
The third root of something is the same as an exponent to the 1/3 power.
(When an exponent is a fraction, the numerator is powers and the denominator finds the root. For example: 3 to the power of 4/2 is multiplied by itself 4 times (81) then the denominator, 2, means we find the square root of it (9). 4/2=2, and 3 to the 2nd power is also 9.)
So that would be 6 to the 1/3 power, then you find the square root of that, so it's (6 to the 1/3 power) to the 1/2 power, and according to the Power Rule (a power on top of a power means you multiply the two powers), that would end up being 1/6.

4x - 2 = 10; 3
4(3) - 2 = 10
12 - 2 = 10
10 = 10

Hi there! To find the circumference of a circle, you do pi (3.14) times the diameter. To find the area of a circle, you do p (3.14) times radius squared. That means you multiply the radius (half the circle) by itself. If you fo the formulas right, here are the right answers for this situation.
Circumference: 24.806 cm
Area: 48.99185 square centimeters
