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:

Step-by-step explanation:
we find the average height of each height first,
t¹= (120+124)/2
=244/2
=122
t²= (124+128)/2
t²= 252/2
t²= 126
t³= (128+132)/2
t³= 260/2
t³= 130
t⁴= (132+136)/2
t⁴= 268/2
t⁴ =134
t⁵= (136+140)/2
t⁵= 276/2
t⁵= 138
so multiplying each height by its frequency we can find the total height, so we have..
total height= (122*7)+(126*8)+(130*13)+(134*9)+(138*3)
= 854+1008+1690+1206+414
= 5172
mean height = total height/total frequency
= 5172/40
=129.3
Factor both the top and bottom.
(2(x-6)(x-2))/((x+6)(x-4))
To find zeros, the numerator must be 0. The denominator cannot be 0 because anything divided by 0 is infinity.
(x-6)=0
x=6
(x-2)=0
x=2
Final answer: x=2, x=6
