Answer:
19,725
Step-by-step explanation:
When you put 31/6 to 5 1/6 and 8 2/9 to 8 2/9 and 11/2 to 5 1/2. Then you change the denominators to 18, so you get 5 3/18 + 8 4/18 - 5 9/18. So you add the 5 3/18 and 8 4/18 to get 13 7/18. Then you subtract 13 7/18 by 5 9/18 to get 7 8/18. simplest form you will get 7 4/9. Your welcome.
C and D
the volume ( V) of a pyramid is found using the formula
V =
× area of base × height
calculating each of the volumes gives
(A) V =
× 10.5 × 6 = 21 in³
(B) V =
× 3.6 × 8 = 9.6 in³
(C) V =
× 4.2 × 12 = 16,8 in³
(D) V =
× 6 × 8.4 = 16.8 in³
C and D have equal volumes
We are given:

There seems to be nothing I can do to simplify this equation. However, I can factor out an
since they both have at least an
. Here is what we get:

This is in the simplest form I can get into. I cannot do anything more to simplify this expression. This is your final answer.
