Answer:
3n(n + 4) = 0
n = 0, -4
Step-by-step explanation:
3n(n + 4) = 0
3n = 0
n = 0
n + 4 = 0
n = -4
David reads 80 pages every day.
Karen reads 25% more pages every day than David reads.
So, Karen reads more pages. She reads a total of 80 + 20 =100 pages.
Rick reads 35% fewer pages per day than Karen. So, Rick reads less pages than Karen. He reads 100 - 35 =65 pages
So, in total the tree friends read = 80+100+65=245 pages.
So, equation becomes
One ratio is 30:40 since 15 times 2 is 30 and 20 times 2 is 40.
Answer:
(4,7) up 3 units and right 6 units is (10,10)
Step-by-step explanation:
(4,7) goes up 3 units, which becomes (4,10). (Go up: 7 + 3 = 10)
(4,10) moves to the right 6 units, which becomes (10,10). (Right: 4 + 6 = 10)
