Answer:
The answer is the option D
; All real numbers
Step-by-step explanation:
we have
![f(x) = 3x + 2](https://tex.z-dn.net/?f=f%28x%29%20%3D%203x%20%2B%202)
![g(x) =7x + 6](https://tex.z-dn.net/?f=g%28x%29%20%3D7x%20%2B%206)
Calculate f(x)*g(x)
![(3x + 2)*(7x+6)](https://tex.z-dn.net/?f=%283x%20%2B%202%29%2A%287x%2B6%29)
Multiply applying the distributive property
![(3x + 2)*(7x+6)=3x*7x+3x*6+2*7x+2*6\\=21x^{2}+18x+14x+12\\=21x^{2}+32x+12](https://tex.z-dn.net/?f=%283x%20%2B%202%29%2A%287x%2B6%29%3D3x%2A7x%2B3x%2A6%2B2%2A7x%2B2%2A6%5C%5C%3D21x%5E%7B2%7D%2B18x%2B14x%2B12%5C%5C%3D21x%5E%7B2%7D%2B32x%2B12)
The domain of the function is the interval------> (-∞,∞)

Answer:
3 cups
Step-by-step explanation:
2/12 = 1/6
1/6 * 3 = 3/18
3 out of 18 cups, so 3 cups.
The best estimate for 1,374 is 1,400 and the best estimate for 6 is 10. This is because anything that is 5 and above you change it. Example: 16 the best estimate for 16 is 20 because 6 is above 5. And when a number is 4 and below you change the number below. Example: 12 the best estimate for 12 is 10 because 2 is below 4. And when the number is perfect like 10, you can keep the number the same. Example:10,20,30,40,50,60etc.
Hope this Helped! :)
