Hi
let call "a number" X.
then we have: 4-13X = X + 8 ..
We have <span>log 1/2 (abc) = log 1/2 a + log 1/2 b + log 1/2 c;</span>
Answer: 2(3c^2+2)
Step-by-step explanation:
Get rid of the parentheses : 5c^2-2c+4 + c^2+2c
Combine any like terms: 5c^2-2c+4 + c^2+2c = 6c^2-2c+4 +2c
Combine like terms: 6c^2-2c+4 +2c = 6c^2+4
Then just factor by grouping: (5c^2-2c+4) + (c^2+2c) = <u>2(3c^2+2)</u>
