Question

Evaluate the expression for c = 8 and d = –3.9.

Write your answer as a decimal or whole number.

cd + c =

Answer 1

To evaluate the expression \( cd + c \) for \( c = 8 \) and \( d = -3.9 \), we can substitute the values of \( c \) and \( d \) into the expression.

First, calculate \( cd \):

\[
cd = 8 \times (-3.9) = -31.2
\]

Next, we add \( c \):

\[
cd + c = -31.2 + 8
\]

Now, perform the addition:

\[
-31.2 + 8 = -23.2
\]

Therefore, the final answer is:

\[
\boxed{-23.2}
\]
