288m^3 is what I got, hope it helps!
X^2+4x+3 or (x+1)(x+3) it depends what the question is asking you to do
Answer:

Step-by-step explanation:

Expanding brackets.

Adding 2m and 6 to both sides.

Combining like terms.

Dividing both sides by 14.

The answer would be D. 18/6. We can figure this out because in the question, it says that each shape is worth one whole. There are three shapes so that means when added, the sum is 3 and 18/6, when reduced is 3.
I hope this helped! :-)
Answer:
y = -2x + 1
Step-by-step explanation:
y = mx + b (m is the slope and b is the y-intercept)
y = mx + 1
Equation for slope: 
(0,1) (1,-1)
=
= -2
y = -2x + 1
