Oh no my parrot is missing
You add 3 1/2 to 2 1/7 to get the tallest skeleton.
3 1/2 = 7/2 and 2 1/7= 15/7
First you find common denominators for both fractions. 2 and 7 go into 14.
2 times 7 equals 14
7/2 * 7 = 49/14
7 times 2 equals 14
15/7 * 2 = 30/14
49/14 + 30/14= 79/14
then you simplify 79/14.... 14*5= 70 and 9 are left over. 5 9/14
The algebraic expression that will represent the perimeter in centimeters of the given rectangle is: 
<em><u>Recall:</u></em>
Perimeter of a rectangle = 2(L + W)
<em>Given the following dimension of a </em><em>rectangle</em><em>:</em>
- width (W) = (8.4x + 2.2) cm
- length (L) = (4.5x + 3.4) cm
To find the expression that represents the perimeter, plug in the given values into the formula for perimeter.
Perimeter = 
Perimeter = 
Perimeter = 
Perimeter = 
Therefore, the algebraic expression that will represent the perimeter in centimeters of the given rectangle is:
