Use the distributive property to simplify: 3(m-1)-(2m+1)How would you do this?
This is all I have 3m-1-2m+1 I don't know if that right or what to do from there. Your help is greatly appreciated.
not right. look at the second term:
-(2m+1)=-2m-1
you missed a sign.
besides that you multiplied the first term incorrectly
3(m-1) is 3m-3 , and not 3m-1
To simplify the expression 3(m-1)-(2m+1) using the distributive property, follow these steps:
Step 1: Distribute the 3 to both terms inside the parentheses by multiplying:
3 * m = 3m
3 * -1 = -3
Step 2: Distribute the -1 to both terms inside the parentheses by multiplying:
-1 * 2m = -2m
-1 * 1 = -1
After applying the distributive property, the expression becomes:
3m - 3 - 2m - 1
Step 3: Combine like terms. Group the terms containing 'm' and the constants separately:
(3m - 2m) + (-3 - 1)
Simplifying the expressions within parentheses:
m + (-4)
Step 4: Simplify the expression by combining the terms:
m - 4
Thus, the simplified form of the expression 3(m-1)-(2m+1) is m - 4.
