Evaluate the expression for j = –15 and k = –2.

jk − j − 16 =

1 answer

To evaluate the expression \( jk - j - 16 \) for \( j = -15 \) and \( k = -2 \), we will first substitute the values of \( j \) and \( k \) into the expression.

  1. Substitute \( j = -15 \) and \( k = -2 \):

\[ jk - j - 16 = (-15)(-2) - (-15) - 16 \]

  1. Calculate \( jk \):

\[ (-15)(-2) = 30 \]

  1. Substitute this result into the expression:

\[ 30 - (-15) - 16 \]

  1. Simplify \( - (-15) \) to \( +15 \):

\[ 30 + 15 - 16 \]

  1. Now calculate \( 30 + 15 \):

\[ 30 + 15 = 45 \]

  1. Finally, subtract \( 16 \):

\[ 45 - 16 = 29 \]

So, the evaluated expression is:

\[ \boxed{29} \]
