Answer:
The expression for the length of the rectangle is 2x + 4
Step-by-step explanation:
The formula for determining the area of a rectangle is expressed as
Area = length × width
The area of a rectangle is expressed as (14x + 28) square feet. If the width of the rectangle is 7 feet, then the expression for the length of the rectangle would be
Length = Area/ width
= (14x + 28)/7
The numerator has a common factor of 7. Therefore, if we factorize 7 out, it becomes
7(2x + 4)/7
Length = 2x + 4
Answer:
yes they are
Step-by-step explanation: because 5x2=10 and 3x2=6 see they both multiply by 2
Formula for finding the area of a triangle:

Where b is the base and h is the height.
Substitute the variables for the values.


A = 270
So, the area is 270 square centimeters.

The range of the averages in a class with a maximum point of 100 point and a minimum point of 20 point is 80 points
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Range is the difference between the maximum value and minimum value of a data set. Hence:
Range = Maximum - Minimum
Let us assume that the maximum point is 100 point and the minimum point is 20 point, hence:
Range = 100 - 20 = 80 points
The range of the averages in a class with a maximum point of 100 point and a minimum point of 20 point is 80 points
