Weight of copper = 1/2w and weight of zinc = 1/2 w
So:-

c = 0.5w*6 + 0.5w*3

c = 3w + 1.5w = 4.5w

this equation is the same as choice A

Help plz solve these equations by completing the square x square + 12x =1

Hitman42 [59]

Answer:

x = - 6 ± $\sqrt{37}$

Step-by-step explanation:

Given

x² + 12x = 1

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(6)x + 36 = 1 + 36

(x + 6)² = 37 ( take the square root of both sides )

x + 6 = ± $\sqrt{37}$ ( subtract 6 from both sides )

x = - 6 ± $\sqrt{37}$ ← exact solutions
