Answer:

20/n+10 = 10/n+20 n

multiply both side n,

n (20/n+10) = n(10/n+20 n)

20+10n = 10+20n^2

20+10n -20 = 10+20n^2 -20

10n  = 20n^2 -10

10n  - 10n  = 20n^2 -10 -10n

0 = = 20n^2 -10 -10n

20n^2 -10 -10n = 0

n = 1 or n = -0.5

with vertices D(2, 5), E(6, 4), and F(3, 3), is reflected across the line A student determined one of the vertices on the image
Nezavi [6.7K]
The vertices of the image reflected over the line y = x are:
D´( 5 , 2 ),  E´( 4, 6 ) and F´( 3, 3 ).
So ( 2, -5 ) is incorrect and it could be incorrectly reflected across over the x-axis.

Two similar pyramids have base edges 3 and 5. Find the following (use a colon between the numbers):
Neko [114]
A) 3 : 5

b) 9 : 25

c) 3 : 5

d) 27 : 125

e) 9 : 25

Because the pyramids are similar, any lengths will have the same ratio, areas the ratios squared and volumes cubed.
(You do not need to know their exact shapes or the formulae for the areas or volume.)
