Answer: Option A.
Step-by-step explanation:
You need to use this formula for calculate the surface area of the right cylinder:
Where "r" is the radius and "h" is the height.
You can identify in the figure that:
Knowing this, you can substitute these values into the formula , therefore you get that the surface area of this right cylinder is:
I will get you started.
x^2+4x-4 = 8
x^2 + 4x - 4 - 8 = 0
x^2 + 4x - 12 = 0
You must now use the quadratic formula.
In the formula, a = 1, b = 4, and c = -12.
Take it from here.
Answer:
the answer is 6x.
Step-by-step explanation:
(x2-x1)/(y2-y1)
(1+2)/(1-13)
3/-12
the slope of the graph is -1/4
