Answer 1

Answer:

The equivalent expression for $4d-4$ is  $4(d-1)$

Step-by-step explanation:

The distance in feet that Karina swims in a race is represented by 4d - 4, where is d is the distance for each lap.

To get equivalent expression we factor the expression 4d-4

Greatest common factor is 4

Factor out 4 from the expression 4d-4

when we factor out 4, we divide each term by 4

$4d-4$

$4(d-1)$

The equivalent expression for $4d-4$ is $4(d-1)$
