Answer:
-11,3
Step-by-step explanation: using foil (x-2)(X+10)=x^2+8x-20
x^2+8x-20-13=13-13 X^2+8x-33=0 factoring you get (x+11)(x-3)=0 so x+11=0
x-3=0
x=-11,3

861 divided by 3:
How many times does 3 go into 8? 2 x 3 = 6
Subtract 6 from 8 to get a remainder of 2, and bring down 6 to get 26.
How many times does 3 go into 26? 8 x 3 = 24
Subtract 24 from 26 to get a remainder of 2, and bring down 1 to get 21.
How many times does 3 go into 21? EXACTLY 7 times. 7 x 3 = 21
Collect all numbers in bold to get…. 287!
Therefore, 861 divided by 3 = 287.
Answer:
A sequence of transformation can move two congruent figures to the same place (vertical / horizontal shifts). This causes them to perfectly overlap, proving their congruency.
A sequence of transformations can be used to show that something is similar, because if one were to transform a figure with only shrinks / stretches, one can shrink / stretch them to make them congruent. If only shrinks or stretches were done, and if the result of the transformation is congruent to the other figure, then the figures are similar (sides are proportional and shrinking/stretching them proves proportionality to other figure).
