Answer:
16x² + 64x + 64
Step-by-step explanation:
Given
A = 16x²
Increasing the sides by 2, substitute x = x + 2 into A
A = 16(x + 2)² ← expand factor using FOIL
= 16(x² + 4x + 4 ) ← distribute
= 16x² + 64x + 64
Answer:
$ -11.61
Step-by-step explanation:
The expected value in this case would be the subtraction between the probability that the draw will win for its value (the prize + value of the ticket) and the value of the ticket for the probability of not winning the draw, thus:
(1/810) * (1100 + 13) - (809/810) * (13)
1,374 -12,984 = -11.61
which means that the expected value is $ -11.61
You know the number has to be divisible by 11. You also know the number is between 100 and 200.
You can list the multiples of 11 in this interval.
110, 121, 132...
You have your answer. The total price is 132 dollars, and the missing digit is 3.
