Answer 2

Finding the Value of p

To find the value of p when the number 2 is a root of the equation 4px = 80, we can use the following steps:

1. Identify the Equation: The given equation is 4px = 80. 2. Use the Definition of a Root: In mathematics, a number is a root of an equation if it satisfies the equation when substituted for the variable.

Solution

To find the value of p when 2 is a root of the equation 4px = 80, we can solve for p as follows:

4px = 80

We know that 2 is a root of the equation, so when x = 2:

4p(2) = 80

Calculation

Let's calculate the value of p:

4p(2) = 80 8p = 80 p = 80 / 8 p = 10

Therefore, when the number 2 is a root of the equation 4px = 80, the value of p is 10.
