Wil give brdainly help asap!! An expression is shown below: 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)

Step-by-step explanation:

A. 1- 4m +12 +20m

2- 24m +12

B. Property of distribution (distribution of 4 to all in parentheses) and property of addition (adding two variables to simplify them = the same it would be if they were separated

C. If you plug in a random number (I'm using 2), you get the same result in all 3 of the expressions

original: 4(2+3+5[2])

8+ 12+ 40 = 60

1: 4(2) + 12+20(2)

8+ 12+ 40 = 60

2: 24(2)+12

48+12=60

i believe the answer is the polygon, heptagon.

i think the correct option is the second option.
