Alex was studying pond life in Echo Park Lake. In two hours, he counted 4 more frogs than turtles. The number of fish he counted was three more than twice the number of
turtles. In total, he counted 54 turtles and fish. How many frogs were there?

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

definitely a. the others have almost all data points on one side of the line.
