Which expression is equivalent to (18x + 9k) + (2x + 6k)?
18x + 9k + 2x + 6k...combine like terms
20x + 15k or it can also be 5(4x + 3k)
Answer:
\(5(4x+3k)\) or \((20x+15k)\)
Step-by-step explanation:
we have
\((18x+9k)+(2x+6k)\)
step 1
Group terms that contain the same variable
\((18x+2x)+(9k+6k)\)
step 2
Combine like terms
\((20x)+(15k)\)
step 3
Factor the number \(5\)
\(5(4x+3k)\)
