Answer:
x=6
y=9
z=10
Step-by-step explanation: The long 20 on the left has 4, 6 and _10_ to make 20. The blank which is 10 is the same length as z. The proportion of 10/15 translates throughout the whole shape. That means it is 6/9 and 4/6.

C
3x^2 * -x =-3x^3
3x^2 * 2. =6x^2
4x* -x =-4x^2
4x * 2 = 8x
-5 * -x = 5x
-5 * 2 = -10
6x^2 + -4x^2 = 2x^2
8x+5x = 13 x
Ans: -3x^3 + 2x^2 + 13x -10
