K12: graph the image of this triangle after a dilation with a scale factor of 3 centered at the origin.
use the polygon tool to graph the triangle.

The points after Dilation are (0,0), (9,-3), and (9,9).

Step-by-step explanation:

The given points are A(0,0), B(3,-1), and C(3,3).

The scale factor is 3.

() = scale factor × () .

If the triangle starts form the origin (0,0) retains the same after the dilation.

= (0,0).

For point B(-1,3),

= 3 × (3,-1).

= (9,-3).

For Point C(3,3),

=  3 × ( 3,3).

= ( 9,9).

Refer the graph for dilated triangle.

stops on an even number.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
