Answer:
y = x² − 6x − 27
Step-by-step explanation:
To distribute, you can use something called FOIL. It stands for First, Outer, Inner, Last.
First, multiply the First term in each factor.
x · x = x²
Now multiply the Outer terms in each factor.
x · 3 = 3x
Next multiply the Inner terms in each factor.
-9 · x = -9x
Finally, multiply the Last terms in each factor.
-9 · 3 = -27
Add them all up:
x² + 3x − 9x − 27
x² − 6x − 27
Answer:
900
Step-by-step explanation:
The figure is a triangular prism
The equation would be V = A * H / 3
V being the volume
A being the area of the pyramids base
H being the height front he base to the top (20)
Base area is 135 (A)
135 * 20 = 2700
2700 divided by 3 = 900
900 is your answer
Plugging in the numbers 7x - 2y = 39 fitted and made sense
Answer:
f(x)= (x+8)^2 + 200
Step-by-step explanation:
-b/2a gives you the x coordinate of the vertex and then plug it in for x to get the y coordinate. Put it in the formula (f()x= (x-h)^2 +k).
H is the x coordinate and K is the y coordinate
