Answer:
The surface area is 78 unit square.
Step-by-step explanation:
Given : The surface area for a rectangular prism with a square base is .
To find : What is the surface area if s=3 and h=5?
Solution :
The surface area for a rectangular prism with a square base is
Substitute, s=3 and h=5
Therefore, The surface area is 78 unit square.
<u>ANSWER:</u>
The solution set for the inequality 7x < 7(x - 2) is null set
<u>SOLUTION:</u>
Given, inequality expression is 7x < 7 × (x – 2)
We have to give the solution set for above inequality expression in the interval notation form.
Now, let us solve the inequality expression for x.
Then, 7x < 7 × (x – 2)
7x < 7 × x – 2 × 7
7x < 7x – 14
7x – (7x – 14) < 0
7x – 7x + 14 < 0
0 + 14 < 0
14 < 0
Which is false, so there exists no solution for x which can satisfy the given equation.
So, the interval solution for given inequality will be null set
Hence, the solution set is
