A universal set U consists of 15 elements. If sets A, B, and Care proper subsets of U and n(U) = 15, n(AB) = n(An C) = n(BNC)=7, n( ABC) = 4, and n(A
UBU C) = 13, determine each of the following.
a) n(AUB)
b) n(AUC)
c) n(
AB)

1,150 give brainliest

step-by-step explanation

2r= 2300

r =1150

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

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
