The 4th one where x is positive y negative
So first we need to make all of the denominators the same. To do this we multiply the top and bottom of the fraction. Multiply the top and bottom of 1/2 to get 4/8. then multiply the top and bottom of 3/4 by 2 to get 6/8. then add the numerators: 4+6+7= 17. Your answer is 17/8.
Keep in mind that we are not changing the quantity of the fractions, we are just changing how the whole is divided. Hope this helps (let me know if I confused you and I'll elaborate with a chart)
Try 18mm that should be the answer
Answer:
We verify: a < b + c; b < a + c; c < a + b;
Only a = 9, b = 12, c = 7 verify the conditions: 9 < 19; 12 < 16; 7 < 21;
The correct answer is D.
Step-by-step explanation:
Answer:
P is the set of problems whose solution times are proportional to polynomials involving N's. ... NP (which stands for nondeterministic polynomial time) is the set of problems whose solutions can be verified in polynomial time. But as far as anyone can tell, many of those problems take exponential time to solve.
