Answer:
1 2
2 6
3 12
Step-by-step explanation:
pattern number is input
tiles number is output.
pattern number 1 has two tiles (first coordinates are (1,2))
pattern number 2 has 6 tiles (second coordinates are (2,6))
pattern number 3 has 12 tiles (last coordinate is (3,12))
answer:
1 2
2 6
3 12
2x^2+20x = -38
2x^2 + 20x + 38 = 0
Divide both sides by 2.
x^2 + 10x + 19 = 0
The quadratic formula works very well here.
Let a = 1, b = 10 and c = 19
x = [-b +- sqrt{b^2 - 4ac}]/(2a)
Plug those values into the formula to find two answers for x.
One is negative and the other positive.
Good luck.
collinear points lies in a single line
that means sum of distance between 2 points is equal to distance between end points.
for example if A B and C lies in a line then
AB + BC = AC
here (1,1) , (2,2) and (3, 3) follows the same rule. ao ans is option D
Answer: 1/(x+2)Step-by-step explanation:=(x-2)(1)/(x-2)(x+2) cancel (x-2)=1/(x+2)

Answer:
16
Step-by-step explanation:
well 1 dozen equals 12 since she has 2 dozens it means she has 24 cookies in total for now. Then you would have to divided by 3. So 24 divided by 3 you will get 8. So 8 cookies per 1/3 but as it says in the problem it was 2/3 which means you duplicate the 8 so it would be 8*2 which is 16 so she has 16 cookies that were oatmeal.
