5/1 + 1/7 this is how the problem is set up do I flip the 5/1 if so what method...

ziro4ka [17]

Use the fraction addition formula. $\frac{a}{b} + \frac{c}{d}= \frac{(ad+bc)}{bd}$

Substitute the numbers into the formula.
a=5, b=1, c=1, d=7

$\frac{5}{1}+ \frac{1}{7} = \frac{12}{35}$

Divide (16x6 − 12x4 + 4x2) by 4x2.

Degger [83]

We know that
<span>(16x6 − 12x4 + 4x2) / 4x2
is equal to
[16x6/4x2]+[-12x4/4x2]+[4x2/4x2]
=[4x4]+[-3x2]+[1]
=4x4-3x2+1

the answer is
</span>4x4-3x2+1<span>

</span>
