The distance in feet that Karina swims in a race is represented by 3d - 3, where d is the distance for each lap. What is an expression equivalent to 3d - 3?

Answer:

3(d- 1) = 3d - 3 as factor or we an re-arrange to show another -3 + 3d so 3(d-1) =3d-3 if asked to rearrange

Step-by-step explanation: 3d -3 = 3(d-3 )An equation states that two expressions are equal in value But if asked to re-arrange then we would show that 3d-3 = -3 + 3d as we we remove the bracket and we would re-arrange

When we use the Associative Property to write an expression equivalent to (w+9)+3 we simply place the number outside of the bracket infront of the bracket and multiply by a number that divides cleanly into it so that 3(d-1) = 3d - 3

Answer:

3(d - 1)

Explanation:

You can factor 3 out from the expression to get 3(d - 1).

Hope this helps :)
