If you would like to know which of the following steps should be performed to eliminate variable d first, you can find this using the following steps:
equation a: 2c = d - 8 /*(-3)
equation b: c = 3d + 8
__________________
-6c = -3d + 24
c = 3d + 8
__________________
-6c + c = -3d + 24 + 3d + 8
-5c = 32
5c = -32
c = -32/5
<span>The correct result would </span>be: <span>multiply equation a by −3.</span>
Answer:
C. 40in
Step-by-step explanation:

so...


576+1024=1600

the missing side = 40in
The approximate volume is 33.5103217
The exact volume is 32/3cm
so the answers would be 32/3 or 33.49
