\( \frac{62222\frac{}{}}{} \)

The weight of 3 eggs is shown. Assuming the three eggs are all the same weight, find the constant of proportionality.

2. Write an equivalent expression fo \( 2(x+6)-8 \)

b). Confirm that \( \phi \) is a porential furetion for \( \hat{F}(z) \) on some region, and state the region. \( \begin{aligned} \phi(x, y, z)= & x \sin z+y \sin x+z \sin y . \\ z(x, y, z)= & (\sin z+y \cos x) i \\ & +(\sin x+z \cos y) j \\ & +(\sin y+x \cos z) k .\end{aligned} \)

Solve for \( b \). \[ -4 b-16=-2 b+18 \]
