Answer: C
<u>Step-by-step explanation:</u>
Replace x with 
and solve.
f(x) = 3x² - 6x - 1
f() = 3()² - 6() - 1
= 3(
) + 4 - 1
= 
+ 3
= + 
= 
Answer:
186.3
To find the answer you have to do inverse operations
9×20.7=186.3
186.3÷20.7=9
Answer:
y + 1 = 3(x - 1)
Step-by-step explanation:
The given point is (1,-1) meaning that x1 = 1 and y1 = -1
The slope of this line is m = 3 because we go up 3 and over to the right 1 (eg: go from the point (1,-1) to (2,2) to see this in action)
Plug these three pieces of info into the point slope formula below
y - y1 = m(x - x1)
y - (-1) = 3(x - 1)
y + 1 = 3(x - 1)
For area A, the width will be √(3A/4), so for the three rugs, the widths are 6 ft, 9 ft, 12 ft. Corresponding lengths are 4/3 times that, so are 8 ft, 12 ft, 16 ft.
The rug dimensions are
.. 6 ft x 8 ft
.. 9 ft x 12 ft
.. 12 ft x 16 ft
Pick the one(s) that are on your list.
