A square has sides of length s. A rectangle is 6 inches shorter than the square and one inch longer. What expression represents the perimeter of the rectangle?

The greatest common factor is 4.

The time at which Harold's fourth class ends is 12:30 PM

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the time at which Harold's fourth class ends be = A

Let the time at which Harold's class starts be = 8:00 AM

The total number of classes for Harold = 4 classes

The duration of each class = 1 hour

The duration of break after each 1 hour class = 10 minutes

So , the equation will be

a)

The time at which Harold's first class starts = 8:00 AM

Now , after first class , the time is = 9:00 AM

And , after the 10 minute break , the time is = 9:10 AM

b)

The time at which Harold's second class starts = 9:10 AM

Now , after second class , the time is = 10:10 AM

And , after the 10 minute break , the time is = 10:20 AM

c)

The time at which Harold's third class starts = 10:20 AM

Now , after third class , the time is = 11:20 AM

And , after the 10 minute break , the time is = 11:30 AM

d)

The time at which Harold's fourth class starts = 11:30 AM

Now , after fourth class , the time is A = 12:30 PM

Therefore , The value of A is 12:30 PM

Hence , The time at which Harold's fourth class ends is 12:30 PM
