help 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)

Part A : 4 (m+3+5m) = 4(6m+3) = 24m+12

Part B: 4 (m+3+5m) combine like terms

           4 (6m+3)    

           24m + 12     Distribution

Part C: m = 3 random number

            4 (3 + 3 + 5(3)) = 24(3)+12

            4(21) = 72 + 12

            84 = 84

Step-by-step explanation:

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

the correct answer is x/3+10≥32

hope this !
