Allison is making bracelets to sell in a school craft show. each bracelet takes her 12 minutes to make, and she's been making bracelets for 120 minutes. she can spend no more than 300 minutes making bracelets. if x represents the remaining number of bracelets that allison can make, which inequality represents the situation?

Let
x-------------> represents the remaining number of bracelets that Allison can make

we know that
1) for the first 120 minutes Allison can make
120/12=10 bracelets

2) for the next 180 minutes Allison can make 
180/12=15 bracelets

therefore
remaining minutes=300-120-------> 180 minutes
so
  -----------> this inequality represents the situation

X^4 + 36x^2 = x^2(x^2+36)= x*x*(x+6i)(x-6i) mark me brainliest
