Question

What is the value of the expression below when w = 4

3w*2 - 3w + 8

Answer 1

To find the value of the expression \( 3w \cdot 2 - 3w + 8 \) when \( w = 4 \), we can substitute \( w \) with \( 4 \):

1. Substitute \( w \) into the expression:
\[
3(4) \cdot 2 - 3(4) + 8
\]

2. Calculate \( 3(4) \):
\[
3(4) = 12
\]

3. Now substitute this back into the expression:
\[
12 \cdot 2 - 12 + 8
\]

4. Next, calculate \( 12 \cdot 2 \):
\[
12 \cdot 2 = 24
\]

5. Now substitute this value back into the expression:
\[
24 - 12 + 8
\]

6. Now do the subtraction and addition from left to right:
- First, \( 24 - 12 = 12 \)
- Then, \( 12 + 8 = 20 \)

Thus, the value of the expression when \( w = 4 \) is \( \boxed{20} \).

Answer 2

20 what?

Answer 3

The value of the expression \( 3w \cdot 2 - 3w + 8 \) when \( w = 4 \) is \( 20 \). In this context, it is simply a numerical value without specific units attached, as the original expression did not include any units. If this expression represents a quantity, it typically would depend on the context in which you're using it (for instance, it could represent dollars, units, etc.).

So, to clearly state: the value is \( 20 \), and it's a numerical result from the calculation.
