Answer: x/y^3
Step-by-step explanation:
So you divide 27/9 which is 3. Then it ix x^7-x^6=x. And then it is y^2-y^5=y3
27*x*x*x*x*x*x*x*y*y/9*x*x*x*x*x*x*y*y*y*y*y
Doing this makes it easier so you cross each variable out for each one in both sides. 3x/y^3 would be your answer.
Answer:
what??
Step-by-step explanation:
Answer:
20 floor
Step-by-step explanation:
16 - 11 = 5 5 + 15 = 20
The elevator is on the 20th floor
After factoring this gives
y ( y + 2) y^2 + 2
------------ = --------- y not equal 3 , 0 or -1
y + 1 y + 1
Its B
