Prove:
Using mathemetical induction:
P(n) =
for n=1
P(n) = = 6
It is divisible by 2 and 3
Now, for n=k,
P(k) =
Assuming P(k) is divisible by 2 and 3:
Now, for n=k+1:
P(k+1) =
P(k+1) =
P(k+1) =
Since, we assumed that P(k) is divisible by 2 and 3, therefore, P(k+1) is also
divisible by 2 and 3.
Hence, by mathematical induction, P(n) = is divisible by 2 and 3 for all positive integer n.
Answer:
The correct option is A) 3 square inches; .
Step-by-step explanation:
It is given that the length of the frame is (2x-3) and the width is (x-2)
The area of the rectangle is:
Where, A is the area l is the length and w is the width of the rectangle.
Put and
in the area of the rectangle.
The area of the frame expressed as a polynomial is .
Now substitute x=3 in .
The area of the frame is 3 square inches.
Hence, the correct option is A) 3 square inches; .
