Because he ended up paying $24 more than the actual price of the drill, this is the amount of interest he paid.
In total, the repairman pays $324 in 6 equal payments. So, each payment was
.
Answer:
2 real roots
Step-by-step explanation:
If the discriminant is >0 then the equation has 2 real roots
If the discriminant is =0 then the equation has 1 real roots
If the discriminant is <0 then the equation has 2 complex roots
since the discriminant is 4, it has 2 real roots
We have that
2x²=450 ----------> x²=450/2----------> x=√225
x1=+15
x2=-15
<span>a reasonable length measurement should be positive
</span>therefore
the answer is
<span>The solutions are -15 and 15, but only 15 is a reasonable side length.</span>
