The change in growth was 14 - 0.5 = 13.5 inches.
Since it is over the course of 5 weeks, divide 13.5 by 5.
13.5/5 = 2.7
2.7 = 270%

The rate of change was 270%. Hope this helps!

the width of a rectangle is x centimetres and its length is (x+ 2) cm. Write down an expression for the perimeter of the rectang
yKpoI14uk [10]

Given:

The width of a rectangle is x centimeters and its length is (x+ 2) cm.

To find:

The expression for the perimeter of the rectangle.

Solution:

We know that, perimeter of a rectangle is

Perimeter=2(Length+Width)

We have,

Width = x cm

Length = (x+2) cm

Putting these values in the above formula, we get

Perimeter=2((x+2)+x)

Perimeter=2(2x+2)

Perimeter=2(2x)+2(2)

Perimeter=4x+4

Therefore, the required expression for the perimeter of the rectangle is (4x+4) cm.
