Answer:
W = X in.
L = (3x - 6) in.
A = L*W = (3x-6)X = 45,
3x^2 - 6x = 45
3x(x-2) = 45,
x(x-2) = 15,
x^2 - 2x - 15 = 0
(x-5)(x+3) = 0,
x-5 = 0,
x = 5 in.
x+3 = 0,
x = -3.
Solution Set: x = 5, and x = -3.
Select + value of X:
x = 5
W = x = 5 in.
L = 3x-6 = 3*5 - 6 = 9 in.
Step-by-step explanation:
So, what I did was multiply 33*6 and got 198 and then 228-198 to find out that the initial fee was 30 dollars. then multiply 33*9+30 to get a 9 month total cost of $327. Hope from here you are able to set up your equation now you have all the information needed :)
1 feet = 12 inches
1 min = 60 s
1 feet/min = 12 in/60 s = 1 in/5 s = 0.2 in/s
The horizontal axis in the coordinate<span> plane is called the x-axis. The vertical axis is called the y-axis. The point at which the two axes intersect is called the </span>origin<span>.</span>
27 is 6% of 450, since 1% of 27 is 4.5, 4.5 * 100 = 450
