All we need to do is use FOIL here to multiply these.

(3x + 2)(3x^2 + 4)

9x^3 + 12x + 6x^2 + 8

Simplify.

Rearrange terms.

9x^3 + 6x^2 + 12x + 8 is the expanded form of the original binomials.

Which table has greater constant of proportionality?
marissa [1.9K]

The table with greater proportionality is table 3.

<h3>What is constant proportionality?</h3>

The constant of proportionality is the ratio between two directly proportional quantities.

As, the constant proportionality is

k= y/x

For table 1,

k = 1/1 = 2/2 =1

For table 2,

k = 6/1= 12/2 = 2

For table 3,

k = 5/1 = 10/2 = 5

For table 4,

k = 4/1 = 8/2 = 4

Hence, table 3 is with greater proportionality.

svp [43]

\huge\text{Hey there!}

\mathsf{23n =2.4}

\large\text{DIVIDE 23 to BOTH SIDES}

\mathsf{\dfrac{23n}{23}=\dfrac{2.4}{23}}

\large\text{Cancel out: }\mathsf{\dfrac{23}{23}}\large\text{ because it gives you 1}

\large\text{Keep: }\mathsf{\dfrac{2.4}{23}}\large\text{ because it helps us solve for n}

\mathsf{n = \dfrac{2.4}{23}}

\mathsd{\dfrac{2.4}{23}= 2.4\div 23\rightarrow \bf 0.104348}

\boxed{\boxed{\large\textsf{Answer: \huge n = \bf 0.104348}}}\huge\checkmark

\boxed{\textsf{NONE OF THE ABOVE is your ANSWER}}

On weekends a movie ticket costs $10.50. form an inequality and solve it to find the maximum number of tickets kate can buy with
Greeley [361]

$10.50

10 Tickets would be $105.00

$105.00 - $10.50 = $94.50 so 9 Tickets would be $94.50

$105.00 + $94.50 = $199.50

$205.00 - $199.50 = $5.50 which isn't enough for another ticket.

10 Tickets + 9 Tickets = 19 Tickets.
