Question

The value of$(-27{\mathrm{x}}^2\mathrm{y})÷(–9\mathrm{xy})$ is

• A. $3\mathrm{xy}$
• B. $-3\mathrm{xy}$
• C. $-3x$
• D. $3x$

Answer 1

The correct option is D

$3x$

Find the value of$(-27{\mathrm{x}}^2\mathrm{y})÷(–9\mathrm{xy})$

$\begin{array}{rcl}(-27{\mathrm{x}}^2\mathrm{y})÷(–9\mathrm{xy})& =& \frac{-27x^{2}y}{-9xy}\\ & =& 3x\\ \therefore (-27{\mathrm{x}}^2\mathrm{y})÷(–9\mathrm{xy})& =& 3x\end{array}$

$\therefore$The correct option is D
