Adding the fractions 3/14+2/21+1/6

NARA [144]

Answer:

$\frac{10}{21}$

Step-by-step explanation:

The LCM of 14, 21 and 6 is 42

We require to change the fractions to fractions with a denominator of 42

$\frac{3(3)}{14(3)}$ + $\frac{2(2)}{21(2)}$ + $\frac{1(7)}{6(7)}$

= $\frac{9}{42}$ + $\frac{4}{42}$ + $\frac{7}{42}$ ← add the numerators, leaving the denominator

= $\frac{9+4+7}{42}$

= $\frac{20}{42}$ ← divide both values by 2

= $\frac{10}{21}$ ← in simplest form

PLEASE HELP Which expression represents the difference quotient of the function f (x) = negative StartRoot 2 x EndRoot?

natali 33 [55]

Answer:

c is the correct option

Step-by-step explanation:

from,

f'(x) = h >0 f(x + h) - f(x)

f(x) = - √2x

f(x + h) = - √(2x + h)

f'(x) = h>0 -√(2x + h) - √2x

rationalize the denominator

= h>0 -√(2x + h) + √2x (-√(2x + h) - √2x)

h (-√(2x + h) - √2x)

= h>0 4x + 2h - 4x

h(-√(2x + h) -√2x)

= h>0 2h

h(-√(2x+h) - √2x)

= h>0  2 

-√(2x+h) - √2x
