Arectangular picture frame has a width of 9 cm and a length of x cm. which expression represents the perimeter of the picture frame? x + 9 2x + 9 2x + 18 2(x+18)

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.

C. because 6÷3=2 so 3 is half of six so 3/6
