Paraphin [41]

Answer:  (x - 3)² = 21

<u>Step-by-step explanation:</u>

x² - 6x + ____ = 12 + ____

       ↓        ↑                 ↑

    \frac{-6}{2} = (-3)^{2}

x² - 6x + <u> 9 </u> = 12 + <u> 9 </u>

       (x - 3)²  =    21

*******************************************************

Answer:  (x - 6)² = 26

<u>Step-by-step explanation:</u>

2x² - 24x = -20

<u>÷2 </u>   <u> ÷2  </u>    <u> ÷2 </u>

 x² -  12x =  -10

x² - 12x + ____ = -10 + ____

       ↓        ↑                   ↑

    \frac{-12}{2} = (-6)^{2}

x² - 12x + <u> 36 </u> = -10 + <u> 36 </u>

       (x - 6)²  =    26

Answer:

SAS Postulate

Step-by-step explanation:

You can use the SAS (side, angle, side) postulate that says "if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent"

Side AB is proportionate to DE and

Side AC is proportionate to DF.

Angle A and Angle D are the same; and is between the two sides

I hope this helps.
