The equation that is equivalent to S=pi r^2 h is h = S/pir^2
<h3>Subject of formula</h3>This is a way of representing a variable with another. Given the equation
S=pi r^2 h
We are to make 'h" the subject of the formula.
Divide both sides by pir^2
S/pir^2 =pi r^2 h/pir^2
h = S/pir^2
Hence the equation that is equivalent to S=pi r^2 h is h = S/pir^2

Answer:
The expression which represent the length of the rectangle is x + 1
Step-by-step explanation:
Given as :
The Area of rectangle = x² - 6 x - 7 square meters
The width of the rectangle = w = x - 7 meters
Let The length of rectangle = L meters
Now, <u>According to question</u>
∵ Area of Rectangle = Length × width
or, x² - 6 x - 7 meters² = L meters × w meters
or, x² - 6 x - 7 = L × (x - 7)
or, x² - 7 x + x - 7 = L × (x - 7)
or, x (x - 7) + 1 (x - 7) = L × (x - 7)
or, (x - 7) (x + 1) = L × (x - 7)
∴ L =
I,e L = x + 1
So, The length of rectangle = L = x + 1
Hence,The expression which represent the length of the rectangle is x + 1 Answer
