Answer:
The inequality that you have is 
. You can use mathematical induction as follows:
Step-by-step explanation:
For 
we have:
Hence, we have that 
Now suppose that the inequality holds for 
and let's proof that the same holds for 
. In fact,
Where the last inequality holds by the induction hypothesis.Then,
Then, the inequality is True whenever 
.
Given
piece of plywood measuring 2 feet 8 inches long by 2 feet 4 inches wide.
What is the area of a piece of plywood .
To proof
Here plywood shape in the form of rectangle.
Formula
Area of rectangle = Length×Breadth
As given in the question
Length =2 feet 8 inches
Breadth = 2 feet 4 inches
First convert feet into inches
1 feet = 12 inches
2 feet 8 inches = 2×12 + 8
= 32 inches
Also
2 feet 4 inches = 2×12 +4
= 28 inches
put is in the above formula
Area of plywood = 32 ×28
= 896 inches²
Therefore option (b) is correct
Hence proved
Answer:
yes of course it is sign but a fact no
Answer: v = 2
Step-by-step explanation:
30-48v+12 = -54
-48v = -54-30-12
= 
v = 2
<span> x^2+8x+12 = </span>(x + 6)(x + 2)
