18. answer the question based on the information below ( im not sure if im right)

You are right!

Step-by-step explanation:

I'll go through why the others aren't right.

B:  BD/XY do not correspond to the similar sides of the two.  BC would need to be over WX and XY would need to be under CD

C:  The second proportion is reversed, you need to keep the shape that has its side in the numerator in the numerator and the one in the denominator int he denominator.

D:  Same as B.  You don't need to actually answer me, but maybe you can tell which sides correspond to those written.

Also let me know if you need any further explanation.

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
