for question 1
Area of Base B =45×25 = 1125 cm²
perimeter of base P = 2(45+25) = 140 cm
Height = 15 cm
Using the formula
Surface area = 2B + Ph
A = 2×1125 + 140×15= 4350 cm²
Voume = Bh = 1125×15= 16875 cm³
For question 2,
Area of base = 7× 5/2= 17.5 cm²
Perimeter of base = (7+7+7) = 21 cm
Surface area = 2B + Ph
Surface area of prism = 2×17.5+ 21×10 = 245cm²
Volume = Bh = 17.5×10 = 175 cm³

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!

7x + 9x + 9x
25
(Then you combine the second like terms, -3, -3, -4)

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

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
