4*pi
Answer:
1
Step-by-step explanation:
m=2
3m²- 2m- 7
3(2)² -2(2) -7
3(4)- 4- 7
12- 4- 7= 1
Answer:
36
Step-by-step explanation:
AOB + BOC = AOC
AOC = 90 since the lines are perpendicular
6x-12 + 3x+30 = 90
Combine like terms
9x + 18 = 90
Subtract 18 from each side
9x+18-18 = 90-18
9x = 72
divide by 9
9x/9 = 72/9
x = 8
AOB = 6x - 12
= 6*8 - 12
= 48 -12
= 36
Answer:

Step-by-step explanation:
We can use algebra to write the decimal in p/q form.






It is now in p/q form.
Step-by-step explanation: So when graphing this problem, we start at -3 on our number line with an open dot because <em>k</em> is less than but not equal to -3. I have shown this in the image attached below.
We then draw an arrow going to the left to represent all number less than -3.
Finally, we put our answer in set notation which is shown below.
{K: k < -3}
All this means is that if we take any number less than -3, this will be a solution for the inequality <em>k < -3</em>.
