Answer:

Step-by-step explanation:

I believe it's 9x2-12x+4 but I'm not quite sure cause we haven't yet gone over this in class.
My friend also believes it is this (she's in a higher level math grade than me). I'm so sorry this isn't more helpful.
This is the graph for y=-2(times)5^x
Hope this helps!
We can use the distance = rate times time formula.
This formula states that if you travel at a constant rate for a certain amount of time, you will know the distance that you traveled.
We know the rate is 3 mph and she hiked for 6 hours.
distance = 3 * 6
distance = 18
So, she traveled 18 miles.
AB = X^2(3X +2)
C^2 = (x - 3)^2
AB - C^2 = 3x^3 + 2x^2 - (x^2 - 6x + 9)
= 3x^3 + x^2 + 6x - 9
