6/11 or about 55%
To put into a fraction the total is the denominator and the 6 would be the numerator as it is the real diamond then divide the numerator by the denominator move your decimal two places round as needed
The answer would be, A) +$2 because he spend $12 but earned $14 so when you subtract 14 and 12 you get $2, which would be his profit
x^2 - 2x = 146
x^2 - 2x - 146 = 0
See attachment. The quadratic formula is needed in this case.
Answer:
4 + 12 + 36 + ...
Step-by-step explanation:
4, 12, 36, ... is a geometric sequence, it has a common ratio of 
When we add the terms of a geometric sequence we get a geometric series.
4+12+36+ ... is a geometric series, it has a common ratio of 
4 + 12 + 20 + ... is not a geometric series because it has no common ratio

The second choice is correct
The answer’s c, y=5/2x+10
