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

Question

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:

\[ \boxed{-23.2} \]
