Question

Evaluate the expression for w = –6, x = 6, and y = –1.9.

Write your answer as a decimal or whole number.

x2 + w − y =

Answer 1

To evaluate the expression \( x^2 + w - y \) for \( w = -6 \), \( x = 6 \), and \( y = -1.9 \), we can substitute these values into the expression.

1. Substitute the values:
\[
x^2 = 6^2 = 36
\]
\[
w = -6
\]
\[
y = -1.9
\]

2. Plug the values into the expression:
\[
x^2 + w - y = 36 + (-6) - (-1.9)
\]

3. Simplify the expression step by step:
- First, calculate \( 36 - 6 \):
\[
36 - 6 = 30
\]
- Now, add \( -(-1.9) \) which is \( +1.9 \):
\[
30 + 1.9 = 31.9
\]

The final result is:
\[
\boxed{31.9}
\]
