Answer:

Equivalent. 0.4(k+3)=0.4k+1.2

Step-by-step explanation:

x means multiplication. k is the variable.

Hi.

So, you have to distribute the 0.4 into the parenthesis to get rid of them. So, you do 0.4xk, which is just 0.4k, and 0.4x3, which is 1.2. So, you have 0.4k+1.2, which means it is Equivalent.
