The perimeter of a rectangle is represented by
2
4x. + 5x -2. the perimeter of a smaller rectangle is represented 2
by x. +3x+5 which polynomial expression best represents how much larger the first rectangle is the smaller rectangle

The perimeter of a rectangle is represented by 4x^2 + 5x − 2. The perimeter of a smaller rectangle is represented by x^2 + 3x + 5. Which polynomial expression BEST represents how much larger the first rectangle is than the smaller rectangle?

A) 3x^2 + 2x − 7

B) 3x^2 + 2x − 3

C) 3x^2 + 8x + 3

D) 5x^2 + 8x − 7

Option A

The polynomial expression best represents how much larger the first rectangle is than the smaller rectangle is

Perimeter of a rectangle is represented by 4x^2 + 5x − 2

Perimeter of a smaller rectangle is represented by x^2 + 3x + 5

To Find : Polynomial expression that represents how much larger the first rectangle is than the smaller rectangle.

Which means we have to find difference between perimeter of both rectangles

Subtract the equation of perimeter of  smaller rectangle from equation of  perimeter of a larger rectangle

Difference = perimeter of a larger rectangle - perimeter of  smaller rectangle

On removing the brackets we get,

Thus option A is correct

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
