Write a polynomial

Question

Write a polynomial to represent the area of the square.

a=s

7x+2

Answer 1

I assume you meant to say that the length of the square is 7x+2. If so, then the area of the square is (7x + 2)². Is "a" the area? If so, then

(7x + 2)² = a,

which you can expand to standard form. There is not much more we can do for you here unless you provide more data or explain the question better.
