Question

Evaluate the expression for n = –1.9 and p = 8.

Write your answer as a decimal or whole number.

n2p − p =

Answer 1

To evaluate the expression \( n^2p - p \) for \( n = -1.9 \) and \( p = 8 \), we start by calculating \( n^2 \).

1. Calculate \( n^2 \):
\[
n^2 = (-1.9)^2 = 3.61
\]

2. Now, substitute \( n^2 \) and \( p \) into the expression:
\[
n^2p - p = 3.61 \times 8 - 8
\]

3. Calculate \( 3.61 \times 8 \):
\[
3.61 \times 8 = 28.88
\]

4. Now, complete the expression:
\[
28.88 - 8 = 20.88
\]

Thus, the evaluated expression is:
\[
\boxed{20.88}
\]
