7) Factor 3x² - 12

So, look at those 2 numbers, and see what they both have in common.

They are both divisible by 3! So, basically you divide 3x² and -12 with 3.

3(x² - 4)

It would be factorized like that because if you multiply 3 by x², you would get 3x², and if you multiplied 3 with -4, you would get -4.

~Hope I helped!~

What steps should be taken to complete the conversion?
dusya [7]

To complete the conversion, the following will be gotten:

12880 m

<h3>How to convert distance?</h3>

Using conversion technique,

8 mi / 1 × 1.61 k / 1 mi × 1000m / 1k

we have to cancel out similar units in the numerator and denominator.

Therefore,

8 mi / 1 × 1.61 k / 1 mi × 1000m / 1k

8 / 1 × 1.61  / 1  × 1000m / 1 = 12.88 / 1 × 1000m

Hence,

12.88 / 1 × 1000m = 12880 m

2 3/8 - 4 1/2 + 3 1/8 - (1/2)
UkoKoshka [18]

let's convert the mixed fractions to improper fractions firstly.

\bf \stackrel{mixed}{2\frac{3}{8}}\implies \cfrac{2\cdot 8+3}{8}\implies \stackrel{improper}{\cfrac{19}{8}}~\hfill \stackrel{mixed}{4\frac{1}{2}}\implies \cfrac{4\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{9}{2}} \\\\\\ \stackrel{mixed}{3\frac{1}{8}}\implies \cfrac{3\cdot 8+1}{8}\implies \stackrel{improper}{\cfrac{25}{8}} \\\\[-0.35em] ~\dotfill

\bf \cfrac{19}{8}-\cfrac{9}{2}+\cfrac{25}{8}-\cfrac{1}{2}\implies \stackrel{\textit{using an LCD of 8}}{\cfrac{(1)19-(4)9+(1)25-(4)1}{8}}\implies \cfrac{19-36+25-4}{8} \\\\\\ \cfrac{4}{8}\implies \cfrac{1}{2}
