Answer:
he studies his math for 15 hours
Step-by-step explanation:
Step-by-step explanation:
(5y+6)^2=24
i.e, 25y^2+60y+36=24
i.e, 25y^2+60y+12=0
i.e, using rule of quadratic equns
y= {-60±√3600-(4×25×12)}/2×25
i.e,y= (-60±√2400)/50
i.e,y= -1.2 ± 0.4√6

A^2 + b^2 =c^2 ; c = hypotenuse, a and b: legs
4^2 + 5^2 = c^2
16 + 25 = c^2
41 =c^2
so c = <span>sqrt(41) = 6.40312424
</span>hypotenuse = 6.40312424
The answer would be 24a+6
