You factor the expression first leaving you with $\frac{3xy(z-1)}{3xy}$
Then you would cancel out 3xy as because there is exactly one on each side. This, in turn, would leave you with z - 1

Answer:

$\frac{12a-14b}{21}$

Step-by-step explanation:

Express the 2 fractions with a common denominator of 21

multiply numerator/denominator of first fraction by 3

multiply numerator/denominator of second fraction by 7

$\frac{4a(3)}{7(3)}$ - $\frac{2b(7)}{3(7)}$

= $\frac{12a}{21}$ - $\frac{14b}{21}$

= $\frac{12a-14b}{21}$

Given the functions:<br> g(n) = 3n - 5<br> f(n) = n2 + 50<br> Find:<br> (g+f)(8)

puteri [66]

Answer:

$(g + f)(8) =133$

Step-by-step explanation:

Given

$g(n) = 3n - 5$

$f(n) = n^2 + 50$

Required

$(g + f)(8)$

This is calculated as:

$(g + f)(n) =g(n) + f(n)$

So, we have:

$(g + f)(n) =3n - 5 + n^2 +50$

$Substitute$ 8 for n

$(g + f)(8) =3*8 - 5 + 8^2 +50$

$(g + f)(8) =24 - 5 + 64 +50$

$(g + f)(8) =133$
