Question 30: Perform the calculation \((4 x y+3 y-5 x) x^{2} y\)

A. \(4 x^{3} y^{2}+3 x^{2} y^{2}-5 x^{3} y\)

B. \(4 x^{3} y^{2}- x^{2} y^{2}-5 x^{3} y\)

C. \(4 x^{2} y^{2}+3 x^{2} y-5 x^{3} y\)

D. \(4 x^{3} y^{2}- x^{2} y^{2}-5 x^{2} y\)

\((4 x y+3 y-5 x) x^{2} y=4 x^{3} y^{2}+3 x^{2} y^{2}-5 x^{3} y\)

« Question 29: Know \( {\frac{{bz – cy}}{a} = \frac{{cx – az}}{b} = \frac{{ay – bx}}{c}}\) (with a, b, c# 0).

Question 30: Find x; y; z knows \(\begin{array}{l} \frac{x}{2} = \frac{y}{{ – 3}} = \frac{z}{8} \end{array}\) knows xyz =24. »
