Answer:
sin^-1 (√111)/2√37) = 60°
Answer:
I think its 7 but im not sure
Six (6) less than (subtraction) six (6) times (multiplication) a number (n) is (=) 12.
6n - 6 = 12
To solve, add 6 to both sides
6n = 18 Dviide both sides by 6
n = 3
<span>Dashed boundary line means there is no equal sign in the problem. That eliminated the first two. Shaded above means it is greater than...
Now turn your inequalities into y = mx + b form
2x - 9y > 2 --- subtract 2x from both sides
-9y > -2x + 2 -- divide by -9...and change inequality sign
y < 2/9x - 2/9 this says y is less then.....we need greater then...this is not it
try the next one...
4x + 7y > 3 --- subtract 4x from both sides
7y > 4x + 3 -- divide by 7
y > 4/7x + 3/7
this says y is greater then...this is the one we want</span>
The answer to your question is D. I hope that this is the answer that you were looking for and it has helped you.
4a^2+7ab-b^2
Step-by-step explanation:
Add the first two equations together:
3a^2-ab-2b^2
+ 2a^2+5ab-3b^2
---------------------------
5a^2+4ab-5b^2
Subtract that answer from the remaining trinomial:
5a^2+4ab-5b^2
- a^2-3ab-4b^2
--------------------------
4a^2+7ab-b^2
