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.
12/5 - 3/10 = 24-3 /10 = 21/10
OR 2.1 in decimal form
D dilation - because they increase/decrease the size of the object but retain its shape.
A, B and C all retain the shape and the size.
