Answer:
D
Step-by-step explanation:
The required standard form is 
<h3>Polynomial function</h3>
Given the polynomial function expressed as:
We are to express this polynomial in standard form
To do that, we will write the degrees of the variables in descending order of magnitude as shown:

Hence the required standard form is

The answer is YES!
You’re gonna have 10x+15+23
Then 10x + 38
And then you are doing next (2x+3) •5 + 23
So you have 2(5x+19)
The last one y>-4
I hope this right
