c2 + c2 + 8 = 8c

2c2 - 8c + 8 = 0

c2 - 4c + 4 = 0

(c - 2)(c - 2) = 0

(c - 2)2 = 0

c - 2 = 0

c = 2

Q: What does c equal if c squared plus c squared plus 8 equals 8c?

8c + 24 + 23 = 71subtract 47 from each side, 8c = 24divide each side by 8, c = 3

It is: 6-11+5-8c+9c = c

-8c + 1 = -3 => -8c = -3 + 1 => -8c = -2 => c = -2/(-8) => c = 1/4 = 0.25

No

If 8c = 60, then c = 60/8 = 7.5.

It is an equation and the value of c is -7

1st:-4c- 11- 4c=4c+12- 4c2nd:-8c- 11+ 11=21+ 113rd:-8c/-8+ 32/-8c=-4

If 8c = 60, then c = 60/8 = 7.5.

If c = 1/8 πn2p, then p = 8c / (πn2)

It is not possible to solve a linear equation in two unknowns without knowing one of them.
