Which expressions are equivalent to x+x+x + 2x+x+x+2x, plus, x, plus, x, plus, 2 ?

Given expression is equivalent to 11x + 2.

Step-by-step explanation:

x+x+x+2x+x+x+2x+x+x+2

Usually we can do these type of additions by grouping the terms with the equivalent powers of x. In the given problem, the power of x is 1 and one constant term is present and so we have to add the x terms and then just writing the constant term with the addition symbol. So we have to rewrite the expression as, 3x+ 2x+ 2x+ 2x+2x+ 2

Adding all the x terms and we will get, 11x + 2.

So the given expression is equivalent to 11x+ 2.
