Everything is divisible by five, so pull out five
5(-k^2+4k-6)
You always start by simplifying.
6b-49=2<span>(</span>b-3) becomes 6b-49=2b-6
From there you can group the b's together by subtracting 2b from both sides, leaving you with 4b-49=-6
Now you can get the b's alone by adding 49 (to cancel out -49) to both sides, giving you 4b=43, You're still trying to get b by itself, so what you'll do is divide both sides by 4, giving you b=10.75
Answer:
Option B. 8.6%
Step-by-step explanation:
Simple index of two stocks: i=?
i=[(5,000*5.1+2,500*7.45)/(5,000*4.5+2,500*7.25)-1]*100%
i=[(25,500+18,625)/(22,500+18,125)-1]*100%
i=[(44,125)/(40,625)-1]*100%
i=[1.086153846-1]*100%
i=[0.086153846]*100%
i=8.6153846%
i=8.6%
Answer:
6u + 72
Step-by-step explanation:
6(u + 12)
Distribute 6 to u and 12
6(u) + 6(12)
6u + 72
