Question

Evaluate the expression for p = 2 and q = –0.9.

Write your answer as a decimal or whole number.

11.9p2q =

Answer 1

To evaluate the expression \( 11.9p^2q \) for \( p = 2 \) and \( q = -0.9 \), we can substitute the values of \( p \) and \( q \) into the expression.

First, calculate \( p^2 \):

\[
p^2 = 2^2 = 4
\]

Now substitute \( p^2 \) and \( q \) into the expression:

\[
11.9p^2q = 11.9 \times 4 \times (-0.9)
\]

Calculate \( 11.9 \times 4 \):

\[
11.9 \times 4 = 47.6
\]

Now multiply \( 47.6 \) by \( -0.9 \):

\[
47.6 \times (-0.9) = -42.84
\]

Therefore, the evaluated expression is:

\[
\boxed{-42.84}
\]
