Which are the solutions of x2=-5x+8?

x = -8/3

Step-by-step explanation:

so we have the given equation x^2 = -5x + 8 right?

lets simplify the x^2   2x = 5x + 8

now lets take the 5x from both sides   -3x = 8

flip the positives and the negatives  3x = -8

and now divide both sides by 3   x = -8/3

x = -2.66666666667

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

answer: (-6,3)
