Answer:
52
Step-by-step explanation:
(I replaced
with
since we are to find
.)
(By the order of operations, we take care of the exponents before whatever else we have here.)
(By the order of operations, we take care of the multiplication as we see if left to right.)
(By the order of operations, we perform addition/subtraction as we see it left to right.)
(This completes the simplification.)
We could have also put this in our calculator as:
4(4)^2 - 2(4) - 4
This would have returned 52.
Answer:
Option D
Step-by-step explanation:
Formula to use: V=
b=base of triangle a=altitude of triangle h=height of prism
Doing is essentially finding the area of the triangle and after multiplying by h will give you the volume of the triangular prism.
Solve: V = or option D
Ps. Altitude is perpendicular or 90 degrees to the side I used for the base, so it wouldn't be option C.
