Question

Evaluate each expression for the given value of the variable. #8

Answer 1

8.

You evaluate the expression given the value of n.

The expression is:

`4(n-1)^2`

We want the value of this expression, GIVEN that n is 6.

So, let's substitute 6 into n and find out the answer. Shown below:

`\begin{gathered} 4(n-1)^2 \\ =4(6-1)^2 \\ =4(5)^2 \\ =4*25 \\ =100 \end{gathered}`
