4(m + 3 + 5m)

part a: write two expressions that are equivalent to the given expression. (3 points)

part b: show that one of your expressions in part a is equivalent to the given expression using algebraic properties. explain which properties you used. (4 points)

part c: show that your other expression from part a is equivalent to the given expression by substituting a number for m. (3 points)

Part A

4m+12+20m

4(6m+3)

Part B

I am going to use the distributive property.

4*6m=24m

4*3=12

24m+12

4*m=4m

4*3=12

4*5m=20m

4m+20m=24m

24m+12

Part C

4*6m=24m

4*3=12

24m+12

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
