Answer:

C

Step-by-step explanation:

N = 5 because there is already 4 terms and we are trying to find the 5th

39 + 7 = 46

So our expression has to equal 46.

C. 18 + 7(5- 1)

18 + 7 x 4

18+ 28

=46

Which shows the equation 12x+4y=480 in general form??
DaniilM [7]

Question is asking about which shows the equation 12x+4y=480 in general form. Options are not given but we can still find the solution.

Given equation 12x+4y=480 is a linear equation so we will need to check general formula of the equation of line. which is given by formula:

ax+by+c=0

Where a, b and c are integers.

Now compare given equation 12x+4y=480 with general formula ax+by+c=0 to find the difference between them.

We see that every term is on the left side of the = in formula but 480 is on the right side of give equation so we will move 480 to the left side.

to do that we subtract 480 from both sides

12x+4y-480=480-480

12x+4y-480=0

Now the new equation looks exactly like the general formula.

Hence final answer is 12x+4y-480=0

The ratio of the lengths of the two legs of a right triangle is 3:4
Snowcat [4.5K]

<em>Greetings from Brasil... </em>

Check Attachment!!!

According to the statement of the question, we have:

a/b = 3/4

<em>Note that according to the attached figure, </em><em>b > a</em><em>, then the correct proportion will be </em><em>a</em><em> to </em><em>3</em><em>, as well as </em><em>b</em><em> to </em><em>4</em><em>, because </em><em>b > a</em><em> and </em><em>4 > 3</em>

Isolating a and b:

a = 3b/4

b = 4a/3

From Pythagoras:

h² = a² + b² - as a = 3b/4 and b = 4a/3, so

<h3>b = 4h/5</h3><h3>a = 6h/5</h3>

For Area:

A = b.a/2

as b = 4h/5 and a = 6h/5, so

<h3>A = 12h/25</h3>
