Answer 2

Correct question: Which of these is a polynomial is One variable?

a) The perimeter of a square whose sidelength is represented by the expression to x.

(b) The area of a square whose side length is represented by the expression 1 + x.

c) the area of a rectangle whose side lengths are represented by the expression 2 + x and x.

(d) The Perimeter of a rectangle whose side lengths are represented by the expressions $x^2+x$ and 5-x​.

Answer:

All of the polynomials in the given options are one variable (Options a, b, c, and d).

• When a polynomial has only one variable, the polynomial is called one variable polynomial.
• In option a, we know that the perimeter of the square, which has its sidelength as x, is $4*x=4x$ which is a one-variable polynomial.
• In option b, the area of the square, which has its side lengths as $1+x$, is $(1+x)*(1+x)=1+x^2+2x$ which is a one-variable polynomial.
• In option c, the area of the rectangle, which has its side lengths as $2+x$ and $x$, is $(2+x)*x=2x+x^2$ which is a one-variable polynomial.
• In option d, the perimeter of the rectangle, which has its side lengths as $x^2+x$ and $5-x$, is $2(x^2+x+5-x)=2x^2+10$ which is also a one-variable polynomial.
