find an expression which represents the sum of (4x + 8) and (8x + 7) in simplest terms.
answer attempt 1 out of 2

Explanation:

Step1: Write the sum expression

To find the sum of \((4x + 8)\) and \((8x + 7)\), we write the expression as \((4x + 8)+(8x + 7)\).

Step2: Combine like terms

First, combine the \(x\)-terms: \(4x+8x = (4 + 8)x=12x\).
Then, combine the constant terms: \(8 + 7=15\).
So the simplified expression is \(12x + 15\).

Answer:

\(12x + 15\)
