4x^2-8

9x^2+16

16x^2-2

49x^2-25

Answers

Answer:

1) The polynomial8x^3+1represents a sum of cubes

2) The polynomial49x^2-25represents a difference of squares

Step-by-step explanation:

1) To find the polynomials represents a sum of cubes :

8x^3+1 represents a sum of cubes

For 8x^3+1

=2^3x^3+1^3

=(2x)^3+1^3

Therefore 8x^3+1=(2x)^3+1^3

Therefore 8x^3+1 represents a sum of cubes

2)To find the polynomials represents a difference of squares :

49x^2-25 represents a difference of squares

For 49x^2-25

=7^2x^2-5^2

=(7x)^2-5^2

Therefore 49x^2-25=(7x)^2-5^2

Therefore 49x^2-25 represents a difference of squares

The length of a rectangle is 2 inches more than twice its width.Write an equation relating the length/of the rectangle to its width w.

Answers

the equation would be: L= 2w + 2

What is equation?

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.

here, we have,

The length of a rectangle is 2 inches more than twice its width.

Let, width = w & length = L

now,

Since the length is 2 inches more than twice the width, the equation would be:

L= 2w + 2

Hence, the equation would be: L= 2w + 2
