Simplifying 0.20 = x^2 / (25 - x):
Multiply both sides by (25 - x)
0.20(25 - x) = x^2
Distributing 0.20:
5 - 0.20x = x^2
Placing all equations on to one side:
x^2 + 0.20x - 5 = 0
Where:
a = 1
b = 0.20
c = -5
The slope is 2 and the y-intercept is -1
The correct answer is 60 percent because all probabilities must add to 100%
I'm guessing since the X makes the length of the triangle 2 more than then first one, that it does the same to the other side.
So the height would be 5 and the length 6. When you plug those into the formula A=1/2 (l×w) it makes:
A=1/2(5×6)
A=1/2 (30)
A=15 ft^2.
So the answer is H
