Hope I helped :)
Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
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
Answer: 8
Step-by-step explanation:
You have to divide 6.7/0.8 and you'll get your answer. She'll be able to use 8 full pieces.
