Determine whether the given segments have the same length. justify your answer

We know the distance formula is

9)

Here A( -4,2) and B(1,4)

So length of AB

=

Also C(2,1)

Length of BC

=

So we can see that length of AB is not equal to length of BC

11.

Now AB =

Also C(2,-1) & D(4,4)

Length of CD

=

Yes AB = CD

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
