Asquare has a side length represented by the polynomial 2x - 3. write a polynomial expression that represents the perimeter of the square

Step-by-step explanation:

1. A square has four sides and all the sides have equal length.

2. Keeping this on mind, you must multply the lenght given in the problem by   4, as you can see below:

3. Therefore, the polynomial expresion that represents the perimeter of the square is .

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.
