Answer:
84
Step-by-step explanation:
f(x) = 3x^2 + 2x – 1
Let x=5
f(5) = 3(5)^2+2(5) -1
= 3*25 +10-1
= 75+10 -1
= 85 -1
Im guessing you meant improper. This means that the numerator is greater than the denominator. An example is 11/4
D,F, E i think these are it
First we will calculate the distance AB.

If C is 5/9 of the distance, mathematically speaking that means:

R: The coordonate of C is 15.
