Answer:
66
Step-by-step explanation:
Replace t with 9 in the equation.

Simplify.


Rounded, it equals 66
Try this solution (based on 3 steps: equation of the line; points in this line; equation of the plane).
(x-6)(x+2)
When you foil it you get x^2+2x-6x-12
After you do this you then add like terms to get x^2-4x-12
Therefore the answer (x-6)(x+2) is correct.
When you know the area and one side of a rectangle, divide the area by the known side to find the length of the other side.
Length = 63/6
Length = 10.5 inches
