(x - 1)2 - 4(X + 1) + 2 = 0
2x - 2 - 4x - 4 + 2 = 0
(2x - 4x) - 4 = 0
-2x = 4
x = 4/-2
x = -2
The answer you are looking for is 25.
2500 / 10² = 25
Since the formula for finding the volume is
V = Pi r² h
5x - 9 = 26
5x - 9 + 9 = 26 + 9
5x = 35
5x/5 = 35/5
X = 7
The value of 4 in 2,402 is 400(four-hundred) and in 64,513 its 4,000(four-thousand)
