Your friend says that enough information is giving to prove that x=12. Is your friend correct?

C. Yes, you can prove that x = 12

Step-by-step explanation:

My friend is correct because by the HL Congruence Theorem, ∆MNP is congruent to ∆MKL. The hypotenuse and leg of one right ∆ is congruent to the hypotenuse and corresponding leg of the other right ∆. So, enough information was given to prove that x = 12.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

570, the answer is 570, hope it
