Answer:

The value of x(x+7) -2, if  x = 3 is 28

Step-by-step explanation:

Given expression is x(x+7)-2

To find,

The value of the expression at x = 3

Solution

Let p(x)  be  x(x+7)-2

The value of the expression at x = 3 is given by p(3)

The value of p(3) is calculated by substituting the value of the variable as '3' in the given expression p(x)

p(3) = 3(3+7) -2

= 3×10 - 2

= 30 - 2

= 28

The value of x(x+7) -2, if  x = 3 is 28
