The side of a square measures (3x − 6) units. part a: what is the expression that represents the area of the square? show your work to receive full credit. (4 points) part b: what are the degree and classification of the expression obtained in part a? (3 points) part c: how does part a demonstrate the closure property for polynomials? (3 points)

See below.

Step-by-step explanation:

A.    the area is the square of the length of a side.

Area = (3x - 6)^2

= 9x^2 - 18x - 18x + 36

= 9x^2 - 36x + 36 (answer).

B. The above answer is a polynomial (trinomial) , degree 2.

C.  It demonstrates that  when we multiply 2 polynomials the answer is also a polynomial.

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.

step-by-step explanation:

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6
