2x+x=36
Kim's Sister age
2x+x=36 Add "x and 2x"
3x=36 Divide both sides by 3
÷3 ÷3
x=12
Kim's sister is 12 years old

15²+20²≠22²
it is not a right angled triangle.
not all sides equal so not an equilateral triangle.
No two sides are equal .
it is not an isosceles triangle.

When factoring either from, you will find two possible values for x. They are different because the first form will be factored to:
(ax+j)(x+k)
While the second form will be factored to:
(x+j)(x+k)
