Let us factor out the 5:
5*x + 5*2y- 5*3
5(x+2y-3)
Therefore, C

You can do this by finding a number close to it, and then finding out how to do it.
For example with 63(square root sign), find out what is close to it.
7x7=49 while 8x8=64
Because of this, we now know that it is between 7 and 8 but is also really close to 8.
Our number could be 7.9

Answer:
1386
Step-by-step explanation:
V=πr²*h
V=22/7*7²*9
V=1386
6x + 4x+6 + 8x+3 = 63
6x+4x+8x = 63 - 3 - 6
18x = 54
x = 54/18
x = 3
Side AB = 6(3) = 18
Side AC = 4(3)+6 = 18
Side BC = 8(3)+3 = 27
