Question 778472: three consecutive numbers are added together and then their sum is multiplied by 3
which equation(s) applies to this
1)3x + 3x + 1 + 3x + 2
2)3x + 3x + 3 + 3x + 6
3)3x + 3(x + 1) + 3(x + 2)
4)x + x + 3 + x + 6

Three consecutive numbers would be:

x = first
x + 1 = second
x + 2 = third {consecutive numbers increase by 1}

x + x + 1 + x + 2 = the sum
3(x + x + 1 + x + 2) {multiplied the sum by 3}
3x + 3x + 3 + 3x + 6 {used distributive property}

3.) 3x + 3x + 3 + 3x + 6
