Step-by-step explanation:
here is answer
Given:
A prism with right triangular base.
Base of triangle = 6 ft
Height of triangle = 8 ft
Height of prism = 7
To find:
The volume of the given prism.
Solution:
The volume of prism is:
...(i)
Where, B is the base area and h is the height of the prism.
In the given figure, the base of the prism is a right angle triangle with legs 6 ft and 8 ft. So, the area of the base is:




Substituting
in (i), we get


Therefore, the volume of the prism is 168 cubic ft.
<h2>Answer:</h2>
3 ( x - 7 ) = 18
<h3>Explanation:</h3>
Let the number be x, so that
According to the Question,
The difference of a number and 7 will be x - 7
Then, three times the difference of a number and 7 is 18 will be 3 ( x - 7 ) = 18.
Answer:
-3
Step-by-step explanation:
To find:
The value of '?' in the following expression:

Solution:
First of all, let us have a look at a few rules of the exponents:


Let us apply these rules and try to find out the missing value ('?') in the given expression.
Left Hand Side (LHS):

Now, let us compare the LHS with RHS, we get:

Dividing with
on both sides:

Therefore, the missing value in the expression is <em>-3.</em>
