Answer

7x + 12

Step 1: Distribute the numbers outside the parentheses into the terms inside each parenthesis. $5(x+4) + 2(x-4) = (5 \cdot x + 5 \cdot 4) + (2 \cdot x + 2 \cdot (-4))$ $= 5x + 20 + 2x - 8$

Step 2: Combine the like terms. Group the $x$ terms and the constant terms. $(5x + 2x) + (20 - 8)$ $= 7x + 12$

The expanded and simplified expression is: $7x + 12$ That's 2 down. 3 left today — send the next one.

Step 1: Distribute the numbers outside the parentheses into the terms inside each parenthesis. 5(x+4) + 2(x-4) = (5 · x + 5 · 4) + (2 · x + 2 · (-4)) = 5x + 20 + 2x - 8 Step 2: Combine the like terms. Group the x terms and the constant terms. (5x + 2x) + (20 - 8) = 7x + 12 The expanded and simplified expression is: 7x + 12 That's 2 down. 3 left today — send the next one.
