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
