Step-by-step explanation:
Answer:
2(s + 5) = 2s + 10, not 2s - 10
2s - 10 = 2s + 10
The answer would be
x² + 18x + 81 = 44 + 81
To complete the square, we look at the value of b (the coefficient of x). We take half of it, then square it; this is the number that gets added to both sides.
18/2 = 9; 9²=81
Therefore we add 81 to both sides.
Answer: B is the answer
Step-by-step explanation:
Answer:
50 times
Step-by-step explanation:
Since the odds of her getting a heads is 50% (1/2) every time she flips the coin. So she should expect to get 50 heads. However this number varies practically because in every single flip there is a 50-50 chance. If she had flipped it infinitely many times then it would be exactly 50%
