Question 3C: Four minus seven equals negative two.
2c-10
The GCF is 3c^5
Without an equality sign the given expression remains as: 18-3c
If you mean: -12 = 3c-9 then c works out as -1
If you're factoring it, it's c(c + 3) c = 0, -3
No, 3c ( c ) = 4c
2bc + 8b - 3c - 12 is an expression, not an equation or inequality. It cannot, therefore have "an answer".

c = 4, c squared = 16, 3c squared = 48, 48 + 9 = 57.
(3c +15)/(c2 - 5) + c/(c + 5)= (3c + 15)/(c - 5)(c + 5) + c/(c + 5)= (3c + 15)/(c - 5)(c + 5) + [c(c - 5)/(c + 5)(c - 5)(since the common denominator is (c + 5)(c - 5)= (3c + 15)/(c - 5)(c + 5) + (c2 - 5c)/(c + 5)(c - 5)= (3c + 15 + c2 - 5c)/(c - 5)(c + 5)= (c2 - 2c + 15)/(c - 5)(c + 5)= [(c - 5)(c + 3)]/(c - 5)(c + 5) (simplify)= (c + 3)/(c + 5)

It's a simple linear equation in one unknown.If you'd like to know what value of 'c' makes it true, you can find it like this:7 = -3c - 2Add 3c to each side:7 + 3c = -2Subtract 7 from each side:3c = -9Divide each side by 3:c = -3
3c-7 = -4
