Answer:
<u>18 of the books are science fiction.</u>
Step-by-step explanation:
24/4 = 6
Science fiction - 6+6+6 = 18
Not science fiction - 24 - 18 = 6
4b²+20b+25=0
Divide everything by 4
b²+5b+ 6.25=0
use the quadratic formula
x= (-b+ or - √b²-4ac) /2a
x= (-5 + or - √5²-4*1*6.25) /2(1)
x= -5/2 so
in this case, b= -5/2
