A is the correct answer.......
Here is the work shown:
x^2-x-20
A is the correct answer because when using the distributive property it is the only example that results in x^2-x-20.
(x+4)(x-5)
x*x=x^2, x*-5=-5x, 4*x=4x, 4*-5=-20. Now combine all alike terms for your final answer. x^2-x-20..

Answer: Fourth option is correct.
Step-by-step explanation:
Since we have given that
Number of cards = 8
Probability of the correctness of the car =
Since there are two possibilities of the card i.e. correct and incorrect.
Let the number of correct answer that his dog chooses be 'x'.
Since we will apply Binomial theorem:
n = 8
p =
So, Mean would be
Hence, Fourth option is correct.
Answer:
8,275,842 digits
Step-by-step explanation:
One more than the floor of the logarithm to the base 37 gives the number of digits. The change of base formula can be used.
Expressed in the base-37 number system, P has 8275842 digits.
Answer:
Energy of each photon will be
Step-by-step explanation:
We have given frequency = 98 MHz
We have given plank's constant
We have to find the energy of each photon
Energy of photon is given by , here h is plank's constant and is frequency
So energy
