Answer:
Step-by-step explanation:
As it is bad written, i suppose it is
Example case:
The second equation is twice the first, so subtracting that from the second equation yields the identity 0 = 0.
This is an identity. It's an equation that holds true (clearly, 0 is the same as 0) regardless of the values of the variables, which means any pair of numbers
is a solution to the system.
Answer:
791.28 cubic feet
Step-by-step explanation:
3.14*6²=113.04
113.04 is the area of the top, sop now we need to multiply it by 7, to get the volume.
113.04*7=791.28
