The following table shows the length and width of a rectangle: Length Width Rectangle A 3x + 2 2x − 1 Which expression is the result of the perimeter of rectangle A and demonstrates the closure property? 2x + 2; the answer is a polynomial 2x + 2; the answer may or may not be a polynomial 10x + 2; the answer is a polynomial 10x + 2; the answer may or may not be a polynomial

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
