how do i write these in equations to represent each situation?

1. the perimeter P of a rectangle is the sum of twice the length L and twice the width W

2. the volume V of a rectangular prism is the product of its three dimensions: length L,width W, and height H

3. The cost C of a telegram of 18 words is the cost F of the first 10 words plus the cost A of each additional word.

1. P=(2L)+(2W)

2. V=LWH
3. C=F+8A

1. Do not need parentheses.

P = 2L + 2W

2. To avoid confusion of LWH being an acronym, indicate multiplication online with an asterisk (*) or parentheses.

V = L * W * H = (L)(W)(H)

To represent each situation as equations, we can follow these steps:

1. The perimeter P of a rectangle is the sum of twice the length L and twice the width W.
- Equation: P = 2L + 2W

2. The volume V of a rectangular prism is the product of its three dimensions: length L, width W, and height H.
- Equation: V = L * W * H

3. The cost C of a telegram of 18 words is the cost F of the first 10 words plus the cost A of each additional word.
- Equation: C = F + (18 - 10) * A

These equations provide an algebraic representation of the given situations, allowing you to use them to calculate specific values or solve related problems.
