Determinar si \( W=\{(x, y): 2 x-3 y=0\} \) es subespacio de \( R^{2} \)

ep 2: Rewrite each term as the product of the GCF and the remaining factor. \[ 54 x y^{6}-36 x^{2} y^{8}+63 x^{7} y^{10} \]

h) \( \left[(1,2)^{4}:(1,2)^{-3}\right] \cdot(1,2)^{-5}= \)

Part \( \mathbf{B} \) b. If the animator changes the equation to \( f(x)=-0.2 x^{2}+20 \), what are the solutions of \( f(x)=0 \) ? List the solutions from least to greatest.

The volume \( V \) of a rectangular solid is equal to the product of its length \( l \), width \( w \), and height \( h \). Solve for \( l \); for \( w \); for \( h \).

Simplify the expression. Write the answer without using negative exponents. All variables represent positive real numbers. \[ \left(\mathrm{mn}^{-2 / 3}\right)^{-3 / 5} \]
