y + 1.2y + 1.2z

A. 2.4yz
B. 1.3y + 1.2z
C. 1.2y^2 + 1.2z
D. 2.2y + 1.2z

is it D???

Yes!

just finished it i'm right it is D

To simplify the expression y + 1.2y + 1.2z, we can combine like terms:

y + 1.2y + 1.2z can be rewritten as (1 + 1.2)y + 1.2z.

Simplifying further, we have 2.2y + 1.2z.

Therefore, the correct answer is D. 2.2y + 1.2z.

To simplify the expression y + 1.2y + 1.2z, we can combine the like terms, which means adding the coefficients of the variables that are the same.

In this case, we have two terms with the variable y: y and 1.2y. To add these terms, we simply add their coefficients:

y + 1.2y = 2.2y

So, the simplified expression becomes 2.2y + 1.2z.

Therefore, the correct option is D. 2.2y + 1.2z.
