10. Solve by factoring: y = x2 - 6x + 9
for y = 0.

x=3

Step-by-step explanation:

y = x^2 - 6x + 9

What two numbers multiply to 9 and add to -6

-3*-3 = 0

-3+-3 = -6

y = (x-3) (x-3)

Setting y = 0

0 =  (x-3) (x-3)

x-3 = 0  x-3 = 0

x=3  x=3

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

the k side
