The answer would be 9v ^4 + 27v ^3 - 36v^2

Step-by-step explanation:

You first would multiply each term in the parenthesis by 9v^2

9v^2 (v^2) + 9v^2 (3v) - 9v^2 (4)

After this you combine the like terms

9v^2 * v^2 is 9v^4

9v^2 * 3v is 27v^3

-9v^2 * 4 is -36v^2

Because you can not simplify it any smaller, this is your final answer

In the first week of January, there are 49 dogs and 28 cats in an animal shelter. Throughout the month, the ratio of dogs to cat

scoundrel [369]

Answer:

35 dogs

Step-by-step explanation:

Given

$49\ dogs: 28\ cats$

Required

Determine the number of dogs for 20 cats

Represent the required number of dogs as a ratio of number of cats

$x : 20\ cats$

So, we have:

$49\ dogs: 28\ cats$

$x : 20\ cats$

Since, the ratio is the same throughout, we have:

$x : 20\ cats$ = $49\ dogs: 28\ cats$

Convert ratio to fraction

$\frac{x}{20} = \frac{49}{28}$

$\frac{x}{20} = \frac{7}{4}$

Multiply through by 20

$x = \frac{7}{4} * 20$

$x = 7 * 5$

$x = 35$

Analyze the following pattern: 1, 2, 5, 10, 17,...

Burka [1]

Step-by-step explanation: Begin by studying the pattern.

Notice that the 1 + 1 is 2, 2 + 3 is 5, 5 + 5 is 10, and 10 + 7 is 17.

So thus far, we're adding 1, 3, 5, and 7. Notice that each of these numbers have a difference of 2 so we would add 9 to get to next number and so on.
