The exact answer is 2*sqrt(5) but I figured it makes more sense to represent distance in terms of the approximate value. Round that however you need to. Your teacher may or may not want you to include the units, so be sure to ask.
=============================================================
Explanation:
This is similar to the previous question I answered earlier. Draw a vertical line straight down from point X until you reach line YZ. Mark point W on this vertical line, and that's also on line YZ.
Point W is the midpoint of YZ, which cuts it in half.
Let's focus on triangle WXY. It's horizontal leg is 8/2 = 4 km. Let a = 4.
For that same triangle, the vertical leg is unknown. We'll call it h. So b = h.
The hypotenuse of this right triangle is YX = 6 km. Let c = 6.
---------------
We have
a = 4b = hc = 6Use the pythagorean theorem from here
a^2 + b^2 = c^2
4^2 + h^2 = 6^2
16 + h^2 = 36
h^2 = 36-16
h^2 = 20
h = sqrt(20)
h = sqrt(4*5)
h = sqrt(4)*sqrt(5)
h = 2*sqrt(5) ..... exact
h = 4.47213595 ..... approximate
h = 4.47 km
The distance is roughly 4.47 km

Answer:
Total angles on a straight Line is 180°
SO
x + 12 + 100 + x = 180
2x + 112=180
2x= 180 - 112
2x =68
x=34°

Christian made smoothies by mixing 2.25 liters of orange juice, 4.75 liters of pineapple juice, 2.5 liters of grape juice. He then poured equal amounts of the mix into 5 different containers for his friends. About how much smoothie did Christian pour in to each container?
Answer:
1.9 Liters (L) per conatiner
Step-by-step explanation:
If we add the 2.25 L of Orange Juice, 4.75 L or Pineapple Juice, and the 2.5 L of Grape Juice we get 9.5. Since there are 5 different containers we need to divide 9.5 by 5 which is 1.9L of smoothie in each container.
Malik's arts and crafts shop has a bolt of crimson velvet 32 meters long. A customer came in during the morning and bought 120 centimeters of the velvet. Another customer bought an additional 14 meters during the afternoon. How much crimson velvet does Malik's shop have left? Write the answer in centimeters.
I hope this helps you sorry to get it wrong
Answer: 16.8 meters
Step-by-step explanation:
32 meter - 120 centimeters = 30.8 meters
30.8 meters - 14 meters = 16.8 meters.

Answer:
Sharon is wrong in step 2.
Step-by-step explanation:
So, basically we need to look at how Sharon step by step solved this problem.
We need to check her work by solving it ourselves, and seeing what she did wrong.
So we have:
9=-3(e-2)
The first thing that we need to do is distrubute the -3 to the e and -2:
9=-3e+6
This is looks like step 1 of Sharon's work.
Now, we need to get -3e alone by getting all the numbers to one side. This means we need to get rid of the 6 by subtracting 6 from both sides:
3=-3e
This doesnt look like what Sharon got.
She has:
15=3w
How did she do this? Note everything from here to the next bolded words explains her incorrect method of solving.
Well, what if we factor out a negative sign, making -3e into 3e?
This would make +6 into -5.
Then you would get:
9=-(3e-6)
The reason why you CANNOT do this is one problem.
Anything that has been factored(basically a value that has had something taken from it), such as the - in our case, cannot be subtracted or added to another number.
The reason you cannot subtract or add a factored number is it changes the value of the answer. So pretty much subtracting and adding factored numbers is BIG NO NO.
Back to how we solve for e.
So we have already gotten to step 2 with:
3=-3e
Lets get e alone by dividing both sides by -3.
3/-3=-1.
-3e/-3 = e.
So our answer, in step 3 is:
-1=e
This is not needed for your answer, and only shows how you can double check your answer.
So if oyu arent 100% sure with this, lets double check.
We got -1 as e, so lets plug it into our orginal equation:
9=-3(e-2)
Plug in -1:
9=-3(-1-2)
Distrubute the -3:
9=3+6
Add together the numbers:
9=9
This is correct!
Hope this helps!

Factorize all of the following
Answer:
(s+16)(s-16)
Step-by-step explanation:
s^2-256
s^2-(16)^2
a^2-b^2= (a+b)(a-b)
(s+16)(s-16)
Answer:
1. 5 ( − 6 ) 2
2. (−16)(+16)
3. ( 7q-3r) ^2
Step-by-step explanation:
5a^2 - 60a + 180 we factor 5 as multiple of a alone (outside of brackets)
Then we keep the common a with its number as 180 doesn't share a
Then we look solely for two numbers that add up to 60 and multiply to 180
We show in the first line what we found and then continue to factor the square of a in format of 5a^(2) and format of -6a-6a to find 5(a2−6a−6a+36) like below until its completed in factored form - 6 -6 would multiply to find +36 and -6-6 subtracts to find -12.
5a^2 - 60a + 180
5( ^ 2 − 1 2 + 3 6)
5 ( ^ 2 − 6 − 6 + 3 6 )
5(a^{2}-6a-6a+36)
5(a2−6a−6a+36)
5 ( ( − 6 ) − 6 ( − 6 ) )
5 ( − 6 ) ( − 6 )
5 ( − 6 ) 2
2.
s^2 - 256
2 + 1 6 − 1 6 − 2 5 6
(+16)−16(+16)
(−16)(+16)
3.
49q^2 + 42qr + 9r^2
(7q )^2 + (7 x 6 + qr) + 3r^2 like by like = 7q and 3r as 3+3 = 6 when squared is our factor outside of brackets and we notice that 6 is not squared in rule.
( 7q-3r) ^2

The figure shows Triangle ABC and some of its transformed images on a coordinate grid:
Which of the four triangles was formed by a translation of Triangle ABC?
1.
2.
3.
4.
Bro pay attention to class...
A "translation" is basically "move" but a fancier word. So as you can see, triangle 1 is from a reflection, triangle 2 is also from a reflection, triangle 3 is from a rotation and we're left with triangle 4, which looks identical to the original triangle. Therefore, it is triangle 4.
