We are asked to find for an expression that represents the perimeter of a picture frame which has a shape of a rectangle. The dimensions given are length of size x cm and a width of size 9 cm.
The formula for the Perimeter of a rectangle is given by
P=2L+2W
where L is the length and W is the width of the rectangle.
Hence,
P=2(x)+2(9)
Simplifying this values would give us a result of,
P=2x+18
Therefore, 2x+18 is the expression that represent the perimeter of the picture frame.
Answer:
True
Step-by-step explanation:
5 X 5 X 5 = 125 because 5 X 5 would be 25. And 25 X 5 would be 125.
Answer:
Area of rectangle, 
.
Step-by-step explanation:
We are given with side lengths of a rectangle are (2x-4) units and (x+1) units. It is required to find the area of rectangle.
The area of a rectangle is equal to the product of its length and breadth. It is given by :
Let us consider, L = (2x-4) units and B = (x+1) units
Plugging the side lengths in above formula:
So, the function that models the area of a rectangle is .
Answer:
I believe this equation is Linear
