Alonzo will run at least 31 miles this week. So far he has run 19 what are the possible numbers of additional miles he will run

12 miles

Step-by-step explanation:

31 > 19 + m                   m = additional miles

31 - 19 = 12 miles left to meet this week's goal of 31 miles

m = 12 miles

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
