8,516.90 has the greater value.
Assuming you mean for x=3
f(3)=2(3)^2-3(3)+4
f(3)=2(9)-9+4
f(3)=18-5
f(3)=13
it is 13
Point A on the graph is rational because the square root of 2.25 is 1.5, which is where point A is located, meaning that point A is is representing a rational number.
What you would do is convert the sizes to equal each other
We need to know the bases first.
Plus, if you are finding the area
the equation would be like this
A: 1/2 (b1+b2) x 12h
