Because there are more than 2 lengths for the sides and because the small triangle faces are right angles we will use this formula:
V=(1/2)bhl
which is equivalent to V=Al (A=(1/2)bh and A is Area)
b=12in
h=35in
l=40in
A=(1/2)•12in•35in
A=(1/2)•420in
A=210in^2
V=Al
V=(210in^2)•40in
V=8400in^3
Making your answer D. 8400 inches cubed

Step-by-step explanation:
Answer:
the line through the points negative 6 comma 0 and 0 comma negative 2
Step-by-step explanation:
Rewrite the equation to something you are familiar with such as the slope intercept form; y = mx + b. This means you need to solve for y.
3x + 9y = -18 --- divide everything by 3.
x + 3y = -6
3y = -6 - x
y = -2 - 1/3x
your slope is -1/3 and your y intercept is - 2.
remember, y-intercept is when x = 0. therefore, when x = 0, y = -2.
write as an ordered pair (0, -2). the only option that has (0, -2) is the second one.
Therefore, the line through the points negative 6 comma 0 and 0 comma negative 2.
