1) In order to solve the equation n/6 = -11.9, you must multiply by 6.

2) $-9m = -45 \\ \\ m = \frac{-45}{-9} \\ \\ m = \frac{45}{9} \\ \\ m = 5 \\ \\ Answer: \fbox {m = 5}$

3) $-14 = \frac{u}{8} \\ \\ -14 \times 8 = u \\ \\ -112 = u \\ \\ u = -112 \\ \\ Answer: \fbox {u = -112}$

4) $-117 = -9h \\ \\ \frac{-117}{-9} = h \\ \\ \frac{117}{9} = h \\ \\ 13 = h \\ \\ h = 13 \\ \\ Answer: \fbox {h = 13}$

5) $\frac{q}{19} = 5 \\ \\ q = 5 \times 19 \\ \\ q = 95 \\ \\ Answer: \fbox {q = 95}$

Combine the following expressions.

Keith_Richards [23]

Answer:

second option

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Simplifying the radicals

$\sqrt{27x^{3} }$

= $\sqrt{9(3)x^2.x}$

= $\sqrt{9}$ × $\sqrt{3}$ × $\sqrt{x^2}$ × $\sqrt{x}$

= 3 × $\sqrt{3}$ × x × $\sqrt{x}$

= 3x $\sqrt{3x}$

-------------------------------

$\sqrt{12x^{3} }$

= $\sqrt{4(3)x^2.x}$

= $\sqrt{4}$ × $\sqrt{3}$ × $\sqrt{x^2}$ × $\sqrt{x}$

= 2 × $\sqrt{3}$ × x × $\sqrt{x}$

= 2x $\sqrt{3x}$

---------------------------------------

Thus

3 × 3x $\sqrt{3x}$ - 2 × 2x $\sqrt{3x}$

= 9x $\sqrt{3x}$ - 4x $\sqrt{3x}$

= 5x $\sqrt{3x}$
