Find the like terms in the expression 1.2y+1.2z

To find the like terms in the expression, we need to identify the terms with the same variable(s) raised to the same power. In this expression, the like terms are those that have either y or z.

The expression is:
y + 1.2y + 1.2z

The terms with y are:
y and 1.2y

The terms with z are:
1.2z

So, the like terms in the expression are:
A. y and 1.2y, and
C. 1.2z

Therefore, the correct answer is D. y, 1.2y, and 1.2z.
