Answer: D. (-2,0) and (9,0)
Step-by-step explanation:
When you equate the factors to 0 you get
(X+2) = 0
X = -2
(X-9) = 0
X= 9
Here the Y value is 0 as you find the factors of x when the Y value is 0.
So the answer is (-2,0) and (9,0)
Answer:
The geometric mean of 2 and 8 comes out to equal 4.
Step-by-step explanation:
The way to determine this is to know that 1 foot is 12 inches (so 2 is 24)
Now the ration that would determine the scale factor of the room is 1:24 (1 inch for every 24 inches)
So the scale factor is 1:24
Now to determine the area we multiply the numbers we have by 2 and change the inches to feet (I hope that makes sense to you, it does to me, I'll show you)
10.25 * 2 = 20.5 ft.
8 * 2 = 16 ft.
now we know the dimensions of the room so we need to find the area.
A=B*H
20.5 * 16 = 328
so the area of the room is 328 ft.²
