The model shows the expression 30 + 12. Which expression is equivalent to this sum? 6 (5) + 2 6 + 5 + 2 6 + 5 (2) 6 (5 + 2)

Answer: 6 * (5 + 2)

Explanation: We want to model the expression 30 + 12 = 42

the options are:

6*5 + 2

6 + 5 + 2

6 + 5*2

6 * (5 + 2)

You can do it strait forward and solve each equation, and you will find the the right solution is 6 * (5 + 2)

because if we took ur initial numbers, 30 and 12, and we divide both of them by 6 (taking 6 as a common factor) we have:

30 + 12 = 6*5 + 6*2

now we can use the distributive property, and we get:

30 + 12 = 6*5 + 6*2 = 6 * (5 + 2)

The answer will be 6 (5+2)

Explain:

You will take 5+2=7 then take 6x7=42

Which is equivalent to the sum above:30+12=42 (42=42)
