I'm really confused and I just don't understand what to do. Please help!
Simplify each expression by combining like terms
-8(n - 5) + 4(n + 1) = ?
Please help!
-8n+40+4n+1=-4n+41
-8(n - 5) + 4(n + 1) =
-8n + 40 + 4n + 4
-4n + 44 =
MsSue can add better than me. Yep, 40+4= 44
Of course! I can certainly help you. To simplify the expression -8(n - 5) + 4(n + 1), we need to distribute the -8 and 4 to the terms inside the parentheses.
Step 1: Distribute -8 to the terms inside the first parentheses:
-8 * n = -8n
-8 * -5 = 40
Step 2: Distribute 4 to the terms inside the second parentheses:
4 * n = 4n
4 * 1 = 4
After distributing, we have:
-8n + 40 + 4n + 4
Step 3: Combine like terms. Like terms have the same variable raised to the same power.
In this case, we have two terms with n, which are -8n and 4n. We can combine them by adding or subtracting the coefficients (the numbers in front):
-8n + 4n = -4n
So, the simplified expression is:
-4n + 40 + 4
Step 4: Combine the constant terms:
40 + 4 = 44
Therefore, the simplified expression is:
-4n + 44
So, the final answer is -4n + 44.
