Evaluate the expression for d = 4 and f = 6.2.

Question

Write your answer as a decimal or whole number.

df + f =

Answer 1

To evaluate the expression \( df + f \) for \( d = 4 \) and \( f = 6.2 \), we can substitute the values of \( d \) and \( f \) into the expression:

1. Calculate \( df \): \[ df = 4 \times 6.2 = 24.8 \]

2. Now add \( f \) to \( df \): \[ df + f = 24.8 + 6.2 = 31.0 \]

Thus, the result of the expression \( df + f \) is \( 31.0 \).
