7. Which property of polynomials says that the sum of two polynomials is also a polynomial?

vlabodo [156]

Answer:

Closure property

Step-by-step explanation:

The closure property of polynomials for addition says that, if we add any two polynomials , the result is also a polynomial.

For is

${x}^{2} + 2$

is a polynomial.

$x - 2$

is also a polynomial.

The sum of the two polynomials is

${x}^{2} + 2 + x - 2 = {x}^{2} + x$

The result:

${x}^{2} + x$

is also a polynomial.

The Perimeter Of A Parallelogram Is 72 Meters. The Width Of The Parallelogram Is 4 Meters Less Than It’s Length. Find The Length

saul85 [17]

The width would be x-4 and

Length would be x

Add all of the sides together

(x-4)+(x-4) + x + x =72,

Which would come out

4x-8=72

Subtract 8 fro, 72 and you get 64

Then divided 64 by 4

So. Width is 16 and length is 20 . given (x-4)
