Answer:
14
Step-by-step explanation:
you can do this two ways:
<u>First: </u>

<u>Second: </u>
Distribute the 3 first

Answer:
Step-by-step explanation:
10x^3 + 35x^2 - 4x - 14
5x^2(2x + 7) - 2(2x + 7)
(5x^2 - 2)(2x + 7)
The volume of the original cone is multiplied by 27
<h3><u>Solution:</u></h3>
We have been given that the height and radius of a cone are each multiplied by 3.
We need to find what effect it has on the volume of the cone.
<em><u>The volume of the original cone is given as follows:</u></em>

Now, the radius and height are multiplied by 3.
Therefore, the new radius is ‘3r’ and the new height is ‘3h’.
Hence the new volume is

original volume of cone x 27 = volume of new cone
Therefore, the original volume of cone is multiplied by 27
W > Y + H/P
W - Y > H/P
P(W - Y) > H
H < P(W - Y)
2x + 7y = 4.....multiply by 2
-4x - 3y = 14
------------------
4x + 14y = 8 (result of multiplying by 2)
-4x - 3y = 14
----------------add
11y = 22
y = 2
2x + 7y = 4
2x + 7(2) = 4
2x + 14 = 4
2x = 4 - 14
2x = - 10
x = -5
solution is : (-5,2)
