The answer to the question is 14
x^4 + 14x^2 + 49
(x^2 + 7)^2
perfect square
Solution:
Number of times a die is rolled = 20
1 - 3=A
2 - 5=B
3 - 4=C
4 - 2=D
5 - 3=E
6 - 3=F
Total number of arrangements of outcomes , when a dice is rolled 20 times given that 1 appear 3 times, 2 appears 5 times, 3 appear 4 times, 4 appear 2 times , 5 appear three times, and 6 appear 3 times
= Arrangement of 6 numbers (A,B,C,D,E,F) in 6! ways and then arranging outcomes
= 6! × [ 3! × 5! × 4!×2!×3!×3!]
= 720 × 6×120×24×72→→[Keep in Mind →n!= n (n-1)(n-2)(n-3)........1]
= 895795200 Ways
Answer:
$1.92
Step-by-step explanation:
To find the cost per bag we divide the total cost by the amount of bags so:
$5.75 / 3 = $1.91666667 per bag, which we can round up to $1.92 per bag.
Area: (2x - 7) * (3*2 + 4x)
(2x - 7) * (6 + 4x)
8x-42
Perimeter: 2(2x - 7) + 2(3*2 + 4x)
∠A+∠B=∠ACD
So, ∠A=93-31=62°
I think it mean that, right?
