Answer :
x = 12

Step-by- step explanation :

Sum of all the sides in a triangle = 180
50+ 7x -17 + 5x +3 = 180
12x + 36 = 180
12x = 180 -36
12x =144
x = 144/12
x = 12

Simplify<br><br> x3-9x<br> divided by <br> x3+x2-6x
almond37 [142]

Step-by-step explanation:

(x^3 - 9x) divided by (x^3 + x^2 - 6x)

= x(x^2 - 9) divided by x(x^2 + x - 6)

= x(x + 3)(x - 3) divided by x(x - 2)(x + 3)

= (x - 3)/(x - 2).
