Answer: second option
Step-by-step explanation:
The formula to convert the temperature from degrees Fahrenheit to degrees Celsius is:
![C=\frac{5}{9}(F-32)](https://tex.z-dn.net/?f=C%3D%5Cfrac%7B5%7D%7B9%7D%28F-32%29)
Where C is the temperature in degrees Celsius and F is the temperature in degrees Fahrenheit.
Having the temperature 59 °F (degrees Fahrenheit), you need to substitute it into the formula
to make the conversion from degrees Fahrenheit to degrees Celsius (C).
Then, you get:
![C=\frac{5}{9}(59-32)\\C=15\°](https://tex.z-dn.net/?f=C%3D%5Cfrac%7B5%7D%7B9%7D%2859-32%29%5C%5CC%3D15%5C%C2%B0)
Marta got the expression
![2x\cdot x^2 + 2x\cdot x + 2x\cdot (-2) + 3\cdot x^2 + 3\cdot x + 3\cdot (-2).](https://tex.z-dn.net/?f=2x%5Ccdot%20x%5E2%20%2B%202x%5Ccdot%20x%20%2B%202x%5Ccdot%20%28-2%29%20%2B%203%5Ccdot%20x%5E2%20%2B%203%5Ccdot%20x%20%2B%203%5Ccdot%20%28-2%29.)
First, note that
![2x\cdot x^2=2x^3,\\2x\cdot x=2x^2,\\2x\cdot (-2)=-4x,\\3\cdot x^2=3x^2,\\ 3\cdot x=3x,\\3\cdot (-2)=-6.](https://tex.z-dn.net/?f=2x%5Ccdot%20x%5E2%3D2x%5E3%2C%5C%5C2x%5Ccdot%20x%3D2x%5E2%2C%5C%5C2x%5Ccdot%20%28-2%29%3D-4x%2C%5C%5C3%5Ccdot%20x%5E2%3D3x%5E2%2C%5C%5C%203%5Ccdot%20x%3D3x%2C%5C%5C3%5Ccdot%20%28-2%29%3D-6.)
Then add terms with the same degree:
![2x^2+3x^2=5x^2,\\-4x+3x=-x.](https://tex.z-dn.net/?f=2x%5E2%2B3x%5E2%3D5x%5E2%2C%5C%5C-4x%2B3x%3D-x.)
At last,
![(2x+3)(x^2 + x - 2)=2x^3+5x^2-x-6.](https://tex.z-dn.net/?f=%282x%2B3%29%28x%5E2%20%2B%20x%20-%202%29%3D2x%5E3%2B5x%5E2-x-6.)
Answer: correct choice is C.
I think the answer is 60 but I’m not for sure
Answer:
68/5 is already in the simplest form. It can be written as 13.6 in decimal form (rounded to 6 decimal places)
