Answer:
Number of catfish = 28
Step-by-step explanation:
Let the number of catfish = c
Number of angle fish = c + 6
Number of guppies = 4*(c + 6) = 4c + 4*6 = 4c + 24
Total fishes = 198
c + c + 6 + 4c + 24 = 198 {Combine like terms}
c + c +4c + 6 + 24 = 198
6c + 30 = 198 {Subtract 30 from both sides}
6c = 198 - 30
6c = 168
c = 168/6 {Divide both sides by 6}
c = 28
1 meter = 100 centimeters
16*100 = 1600 cm
1600/70 = 22.86
The largest number of fence posts that can be possibly cut from the log is 22.

Answer: x=−2+√11 or x=−2−√11
Step-by-step explanation:
x2+4x−7=7−7
x2+4x−7=0
For this equation: a=1, b=4, c=-7
1x2+4x+−7=0
Step 2: Use quadratic formula with a=1, b=4, c=-7.
x=
−b±√b2−4ac
2a
x=
−(4)±√(4)2−4(1)(−7)
2(1)
x=
−4±√44
2
x=−2+√11 or x=−2−√11
