<u>Answer:</u>
Two times the difference of a number x and 7 plus 10.
<u>Step-by-step explanation:</u>
We are to write a phrase which matches the following algebraic expression below:

We can see that there is a bracket with a coefficient outside it so we can express it as:
<em>'Two times the difference of a number x and 7'.</em>
While + 10 can be added to it to complete the phrase:
Two times the difference of a number x and 7 plus 10.
To find the value of y in the given equation, substitute the given value of x to the equation.
y = 4x + 2x² -x³
Substitute 2 for all x's.
y = 4(2) + 2(2²) - 2³ = 8
Therefore, the value of y is 8.
