A and D

Step-by-step explanation:

0.45 - 0.23 = 0.22

0.45(8) = 3.60

First degree binomial

Explanation:

The classification of an expression is based on two factors:

1- the highest degree

2- the number of terms

The given expression is:

5x + 2

We can note that:

1- The highest power is 1, therefore, this is a first degree expression

2- The expression has two terms, therefore, it is a polynomial

Combining the above, we can conclude that the given expression is a first degree binomial

Hope this helps :)
