Step-by-step explanation:
9.2 < 3x = 21.25
3x = 21.25 - 9.2
3x = 12.05
x = 18.2
Value of the expression will be 7
<u><em>Explanation</em></u>
Given value of the variables are :
and 
Given expression: 
So, <u>plugging the values</u> of
and
into the above expression, we will get...

So, the value of the expression will be 7.
To find the area, your just supposed to multiply
Answer:
168 cm³
Step-by-step explanation:
The base of the prism is a right triangle whose hypotenuse is 10 cm and one other side is 6 cm.
So, the third side of the triangle =
cm.
{Since we have applied the Pythagoras theorem.}
Hence, the area of the base triangle is
cm².
Therefore, the volume of the prism is =
cm³ {Since volume of a prism is given by ( Area of the base triangle ) × ( Height of the prism )}
