3/5 because it can't be 1/6 or 1/2 because they are 50% or smaller. Also it is 2/5 because if you count 20, 40, 60... up to 100 the third number is 50.
2=9x+5 I think this is how you do it because you say that it have to equal to 2
The solutions to the equation are
.
You can find the answer to any quadratic by using the quadratic formula. The formula is below.

Then find a (the number attached to x^2), b (the number attached to x) and c (the constant). This will allow you to plug in and solve.




Given:
x y
2 3
7 3
7 10
2 10
It is easier to graph these vertices to avoid confusion.
Length: basis is the y-values : 10 - 3 = 7 units
Width: basis is the x-values: 7-2 = 5 units
Area = Length * Width
A = 7 units * 5 units
A = 35 units² Choice D.
