Janet earns more money because she gets paid $8 every 30minutes and in other words is that per hour she gets paid $16. Whereas Sam gets paid $15 every hour. The amount paid at the start determines who gets more
-9u + 3u = 9 + 9
-6u = 18
u = -18/6
u = -3
Thus, u is equal to -3
Answer: the question can only be simplified to -8z-12 because there is no equal sign.
Step-by-step explanation:
(4z - 12) - 12z
-8z-12
This one is prime. The sum of two squares doesn't factor.
The more interesting case is q^2-1, which factors into (q-1)(q+1).
