-8 times -7 equals 56. there for the answer is -7.
A is the answer as in both cases E is 90 degrees
X + (2 10)/(30 x)
The gcd of 10 and 30 is 10, so 10/30 = (10×1)/(10×3) = 10/10×1/3 = 1/3:
x + 2/(3 x)
Put each term in x + 2/(x 3) over the common denominator 3 x: x + 2/(x 3) = (3 x^2)/(3 x) + 2/(3 x):
(3 x^2)/(3 x) + 2/(3 x)
(3 x^2)/(3 x) + 2/(3 x) = (3 x^2 + 2)/(3 x):
Answer: (3 x^2 + 2)/(3 x)
Answer:
8
Step-by-step explanation:
The diagram shows 8 different endpoints, so there are 8 different possible outcomes.
You can list all outcomes:
HHH
HHT
HTH
HTT
THH
THT
TTH
TTT
where H - head, T - tail
