2 (18cm) + 2 (3cm) = perimeter

36cm + 6cm = P

The perimeter is 42 cm.

Using the expression 2l + 2w, it would be 2(18) + 2(3)

2(18) = 36

2(3) = 6

36 + 6 = 42

<h3>What are Arithmetic operations?</h3>

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 12 -2 = 10

* Multiplication operation: Multiplies values on either side of the operator

For example 12*2 = 24

You have accepted a job offer at an annual salary of $36,980.

This salary includes a year-end bonus of $2900

So your gross pay = 36980 + 2900 = 15952

You are paid twice per month

12 months × 2 checks = 24 paychecks

15952/ 25= 1595.2

Hence, your gross pay will be $1595.2 for each paycheck

1. A recipe calls for 1 1/2 cups of flour, 3/4 cup of white sugar, and 1/3 cup of brown sugar. The recipe makes 6 servings.
Nastasia [14]
1 1/2 divided by 6 is 1/4, so 1/4 of a cup of flour for each serving.

12 is the common denominator between 3/4 and 1/3,so 9/12 and 4/12,add them and you get 13/12,take 12 away from the top number and you get 1 1/12, so           1 1/12 is answer for 2

remember,1 serving is 1/4 of a cu of flour, and 9 is only 3 more than 6,so you just add in 3/4 to the flour, and that yould make it 2 1/4 cups of flour.


i hope this helps
