<h3>What is division?</h3>

Division means the separation of something into different parts, sharing of something among different people, places, etc.

The expressions are given below.

(9.6 x 10⁻⁸) and (3.2 x 10⁴)

Then the quotient of the expressions will be

⇒ (9.6 x 10⁻⁸) / (3.2 x 10⁴)

⇒ (3 x 10⁻⁸) / (10⁴)

⇒ 3 x 10⁻⁸ x 10⁻⁴

⇒ 3 x 10⁻⁸⁻⁴

⇒ 3 x 10⁻¹²

Then the correct option is D.

Answer:

Step-by-step explanation:

Width = 5v - 4w

Length = 3v + 7w

Perimeter = 2*(length + width)

               = 2* (3v + 7w + 5v - 4w)

               = 2* (3v + 5v + <u>7w - 4w)</u>  {Combine like terms}

                = 2* (8v + <u> 3w)</u>

                 = 2*8v + 2*3w

                 = 16v + 6w
