Length= 5x-2 because 15x^2-10x-9x+6 is (5x-2) and (3x-2)
LW=A
L={(5x-2)(3x-2)}/(3x-2)=5x-2
You will have a better chance of winning because your chance before you opened the first door was 1/3 (since there was 3 doors) but now, you have 2 doors left, so it is a 50% chance that you will win.
Answer: the answer is D
Step-by-step explanation:V = pi (d/2)^2 * h
V = pi (d^2 / 4) * h
h = 4V / ( pi * d^2) (meters)
15 + .65x = 80
15 + .65x = 80
15 - 15 + .65x = 80 - 15
.65/.65x = 65/.65
x = 100
