All of the 8th grade students in a school have to take at least one of the two electives offered. The number in the Technology elective class is 25, number of students in the Art elective class is 15, and 7 are in both Technology and Art classes. How many 8th grade students are there in school

47

Step-by-step explanation:

Add all the numbers together in order to receive the total number of 8th grade students.

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

they aren't great and cause destruction, idk man
