Answer:
x=3
Step-by-step explanation:
the volume of the prism with triangular base is 54 unit³
The base is a triangle with, base i.e 4 units and height i.e x units
Also, height of the prism = 3x
So, volume of the prism is,
And
,
Then,
As the volume is given as 54 unit³, hence
6x²=54
x²=9
x=3

Answer:
The C is right
Step-by-step explanation:
5x – y = 8 ( multiple both sides by 4)
20 x – 4y = 24
we have
20x –4 y = 32
20 x – 4y = 24
----------------------------------( sustract side by side)
0 = 32-24
or 0 = 8
Impossible
There is so solution.
The C is right.
I believe the answer is £7.96
