Find area of each of the faces.
4 triangle faces: 1/2 x b x h
1/2 x 8 x 10 = 40
40 x 4 (because there are four of them) = 160
one square bottom:
s^2
8^2 = 64
160 + 64 = 224
Yes.The second factor is the difference of 2 squares,
so the second factor alone becomes
(x² - 4) = (x + 2) (x - 2)
Take the average, which always lies in the middle of any two numbers:
(1413/5689 + 1838/7370) / 2 = 5217548/20963965
To get another number, take the average of this number with any of the first two. For example,
(1413/5689 + 5217548/20963965)/2 = 10424453/41927930
Notice that
1413/5689 ≈ 0.248<u>374</u>
10424453/41927930 ≈ 0.248<u>628</u> … … … (the second average, between the first number and the first average)
5217548/20963965 ≈ 0.248<u>882</u> … … … (the first average of the given two numbers)
1838/7370 ≈ 0.24<u>9389</u>

Answer:
e(x) x2+6x+21=53
m(x) 8x=32
v(x) 31x=124
therefore v(x) is the correct answer
