Answer:

= (x + 6) (x - 8)

Step-by-step explanation:

x² - 2x - 48

break the expression into groups:

= (x² + 6x) + (-8x - 48)

= x (x + 6) - 8(x + 6)

= (x + 6) (x - 8)

We need a 2 and a 3 to produce a six. Because we are dividing by " $2^{4}*3^{2}$ "...

We need a " $2^{5}*3^{3}$ " in the numerator.

In this way, x+y = 5+3 = 8.

answer: 8

Solve for r. p = 4r 3t

lara31 [8.8K]

P = 4r + 3t
4r = p - 3t
r = (p - 3t)/4

Given : Anne buys 600 packets of mints.

Given : Of these 600 packets of mints, 34% are small packets and 40% are large packets.

$:\implies$ Total % of small and large packets is (34 + 40) = 74%

It means : The remaining percentage is of the medium packets of mints which were brought by Anne.

$:\implies$ % of medium packets brought by Anne : (100 - 74) = 26%

$:\implies \textsf{Number of medium packets brought by Anne : $\left(\dfrac{26}{100} \times 600\right)$}$

$:\implies \textsf{Number of medium packets brought by Anne : $\left(26 \times 6\right)$ = 156}$

Given : Ben buys 400 packets of mints.

$\textsf{Given : Of these 400 packets of mints, $\dfrac{3}{10}$ are small and $\dfrac{1}{10}$ are large}$

$\implies \textsf{Total fraction of small and large packets brought by Ben :$\left(\dfrac{3}{10} + \dfrac{1}{10}\right)$}$

It means : The remaining fraction is of the medium packets of mints which were brought by Ben.

$\implies \textsf{Fraction of medium packets brought by Ben : $\left(1 - \dfrac{3}{10} - \dfrac{1}{10}\right)$}$

$\implies \textsf{Fraction of medium packets brought by Ben : $\left(1 - \dfrac{4}{10}\right)$ = $\dfrac{6}{10}$}$

$:\implies \textsf{Number of medium packets brought by Ben : $\left(\dfrac{6}{10} \times 400\right)$}$

$:\implies \textsf{Number of medium packets brought by Anne : $\left(6 \times 40\right)$ = 240}$

Given : Chas buys 210 small packets of mints.

Given : Number of small packets : number of medium packets = 3 : 4

$\implies \mathsf{\dfrac{210}{number \ of \ medium \ packets} = \dfrac{3}{4}}$

$\implies \mathsf{Number \ of \ medium \ packets = \left(210 \times \dfrac{4}{3}\right)}$

$\implies \textsf{Number of medium packets brought by Chas = 280}$

Total number of medium packets of mints brought by these three shop keepers (Anne, Ben, Chas) are :

$:\implies$ (156 + 240 + 280)

$:\implies$ 676

Harry says that 1/4+1/8=2/8. jane says 1/4+1/8=3/8.whose answer make sense and whose amswer is nonsense? exolain your resoning.

pashok25 [27]

Jane is correct.

Work:

1/4 = 2/8
So 1/8 + 2/8 = 3/8

Henry is incorrect.
