1. Take your 13.75 and 5 1/2 and put it into a dividing table
_______
5.5 I13.75
you need to get your decimal out of deviser (5.5) will now be (55) because you moved the decimal over there you also need to move the decimal that is on the inside to and it will be (137.5)
2. When you divide you would get 2.5
3. Now you would know how much the tree grew over the 5 1/2 years.

<span>X^3+6x^2-17x+2-x^3-x^2-11x+36 = </span>5x^2 - 28x + 38
I wouldn't say so, as if you rearrange that equation you get sqr root y = 12 - 4x. Then you square everything to get the value of y so you would end up with 144 - 16x^2.
Therefore, the x value has a power, so it would be a curved line
