Please help asap question four*

I'm pretty sure the answer is 9

Step-by-step explanation:

Since 4 x 9 =36

which means it would be                 x                y

                                                          1                4

                                                          2               8

                                                          3               12

                                                          4               16

and so on

(please let me know if I'm correct, thank you)

b) well because you get well

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
