Problem 5
Question
Evaluate each algebraic expression for the given value or values of the variable(s). $$x^{2}+3 x, \text { for } x=8$$
Step-by-Step Solution
Verified Answer
The value of the algebraic expression for \(x = 8\) is 88.
1Step 1: Identify the given value of x
The problem has given the value of variable x, which is 8.
2Step 2: Substitute the value of x
Substitute the given value \(x = 8\) into \(x^2 + 3x\). This gives you \(8^{2} + 3(8)\).
3Step 3: Calculate the values
Calculate the values: \(64 + 24 = 88\).
