The answer would be C. 14
Answer:
c
Step-by-step explanation:
quadratic formula: -b±√b²-4ac/ 2a
a= -10
b= 12
c= -9
-12±√144- 4(-10)(-9)/ 2(-10)
-12±√144- 360/ -20
-12±√-216/-20
6±3i√6/ 10
simplify: 3/5± 3i√6/10
Step-by-step explanation:
(12x+5)=(17x-5)
- 5+5=17x-12x
- 10=5x
- x=10/3
- x=2

Answer:
80 copies
Step-by-step explanation:
4 minutes= 240 seconds. So I did 240 seconds divided by 3 seconds (one copy is made in that time) then you get 80. I don't know if that explanation make sense but the math checks out.
21 and -4, because -4x21 = -84, and 21+-4 (– 4) = 17
