Answer:3x+8Step-by-step explanation:First, we can write the sum into a mathematical expression:The sum of (x+5) and (2x+3)(x+5)+(2x+3)However, we do not need the parenthesis. It is unnecesarry here as we are just adding the two parts:x+5+2x+3Using commutative property, we can rearrange the symbols so that the x's are with each other and the numbers are with each other:x+2x+5+3Now we can simplify the expression:3x+8Hope this helped :)
