What is the difference of the polynomials? (12x?-1172-13x)- (5x2–14y2–9x
O 7x2 + 3y2-4x
O 7x2-3y2-4x
O 7x2 - 25y2 - 22x
O 17x2 - 25y2 - 22X

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: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest

hi! i think the answer is 1/2 : )
