X^3 + 10x^2 + 24x
divide by x
x(x^2 + 10x + 24)
factor it
x(x+4)(x + 6)
now solve for x
the answer is -6,0,-4
103, as 6*10=60, so she has added 60 pieces

C.36,565 I hope this helps
146 or 27 because 27 with 73 = 100% or 219-73=146
Answer:
We only need to calculate the 15% of 44.99 and 49.99 and sum them, for that, we have to multiply each number by 0.15:
44.99 * 0.15 + 49.99 * 0.15 = 14.27
He saved 14.25 (you should put the unit it's).
We could also have done a rule of three (which is what we have really did before)
44.99 - 100%
x - 15%
x =
=. 6.75
49.99 - 100%
x - 15%
x =
= 7.5
6.75 + 7.5 = 14.25
