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?

3(d - 1)

Step-by-step explanation:

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

Hope this helps :)

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

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
