Rectangle abcd was dilated to create rectangle a'b'c'd' using point r as the center of dilation. if rd = 15, what is rd'?

we have a rectangle abcd dilated to center a'b'c'd'.

no we have two rectangles we know that in rectangles we have parallel and equal sides we have to use ratio of corresponding sides

ab and a'b

a'b': ab=

we have rd=15 and we need to find rd'.

we know that ratio corresponding sides are always equal.

so rd' will be 1: 3 of rd

10x

step-by-step explanation:

the greatest common factor 30 and 20 is 10

5 is a common factor of 30 and 20 but 10 is also a factor and 10 is greater than 5 so 5 will definitely not be apart of our answer

now the most amount of x's you factor our is just 1 factor of 1

so 10x the gcf of the terms in the polynomial
