79

Step-by-step explanation:

equation:

18x - 8 + 11x = 20x +19

Add like terms:

29x - 8 = 20x + 19

add 8 to both sides:

29x = 20x + 27

subtract 20x from btoh side:

9x = 27

Divide both sides by 9:

x = 3

substitute x into the equation for SU

SU = 20(3) + 19

Solve:

SU = 79

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
