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:4m + 12 + 20m

2 (2m + 6 + 10m)

Part B: 2 (2m + 6 + 10m) = 4(m + 3 + 5m)

4m + 12 + 20m = 4m + 12 + 20m

24m + 12 = 24m + 12

Part C: if m equals 2,

4(m + 3 + 5m)

compile it down

4(2 + 3 + 5 x 2)

4(5 + 5 x 2)

4(10 x 2)

4(20)

4 times 20

80

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
