Factor by groupins
x^2 + xy - 2x - 2y
= x(x + y) - 2(x + y)
= (x - 2(x + y)
Step-by-step explanation:
x=y
y=1/z^3
Now,
for equation,
x=y=1/z^3
The answer is c or the third option. If we start at one we get (4(1)-9)=-5, then we can do 2 and we get (4(2)-9)=-1. Lets do 3 (4(3)-9)=3. Now 4 (4(4)-9)=7. Now 5 and our last one (4(5)-9)=11. Now notice we get -5+-1+3+7+11.
Your answer is -43/6
1/12(4+6x3)-9
=1/12(22)-9
=11/6-9
=11/6-54/6
=-43/6
