Step-by-step explanation:

I think you missed attaching the photo, please see my attachment.

And the correct answer is C,

When you look at where the arc meets the parallel lines, if you create a seam between two points, you get a straight line parallel to the horizontal lines  so it makes the corresponding angles are congruent.

Find the value of x in the triangle shown below.<br> 13<br> 5<br> х
katen-ka-za [31]

Answer:

x=12

Step-by-step explanation:

This is a right triangle, so the Pythagorean theorem can be used. The Pythagorean theorem states that C^2=a^2+b^2 where C is the hypotenuse and a and b are legs. In this question, we are given a and C. So, plugin 13 for C and 5 for a and solve for b. Once you rearrange the equation you get, b=\sqrt{13^2-5^2}. Next, solve what is under the root to get, b=\sqrt{144}. Finally, square root 144 for the final answer b=12.

Plz help! It’s not hard I just don’t properly understand
jonny [76]

Answer:

a_{13}=2(13)+13=39

39 is the 13th term

Step-by-step explanation:

Okay so essentially the a_n is just a substitute for x.

See how in the equation they put n into the x spot:

y=mx+b\\a_n=mn+b\\a_n=2n+13

They changed the variable names:

y=a_n\\m=2\\n=x\\b=13

Now we know what the n actually means, plus when they ask about the terms youre trying to find it's based off of that n:

When they say, 13 term, they mean a_{13} which would be the 13th answer in the series.  So the first term would be based off of a_1

a_1=2(1)+13\\a_1=15

So whatever number is in the n position by a is what you'll be plugging into the x spot.

y=mx+b\\a_n=2n+13\\a_1=2(1)+13=15\\a_2=2(2)+13=17\\a_3=2(3)+13=19\\a_4=2(4)+13=21\\a_5=2(5) +13=23\\a_6=2(6)+13=25\\a_7=2(7)+13=27\\a_8=2(8) +13=29\\a_9=2(9)+13=31\\a_{10}=2(10)+13=33\\a_{11}=2(11)+13=35\\a_{12}=2(12)+13=37\\a_{13}=2(13)+13=39

These are all the answers leading up to the 13th term they asked for, and you can continue thus same equation with whatever number you can put into the n space.

What is the sum? StartFraction 3 Over x squared minus 9 EndFraction + StartFraction 5 Over x + 3 EndFraction
Karolina [17]

Answer:

The answer is:

\frac{5 x - 12}{(x + 3)(x - 3)}

Step-by-step explanation:

\frac{3}{x ^{2}  - 9}  +  \frac{5}{x + 3}

First, we have to make the denorminator same by multiplying:

\frac{3}{(x + 3)(x - 3)}  +  \frac{5}{x + 3}

\frac{3}{(x + 3)(x - 3)}  +  \frac{5(x - 3)}{(x + 3)(x - 3)}

Then, we can add up everything together:

\frac{3 + 5x - 15}{(x + 3(x - 3)}

\frac{5x - 12}{(x + 3)(x - 3)}

(Sorry if being messy)
