Multiply the following using the vertical method

Option C is correct.

Step-by-step explanation:

We need to multiply the following terms using vertical multiplication method

 3x^2-5x+1

x x^2+2x+4

The vertical multiplication is shown in the figure attached.

The result is: 3x^4+x^3+3x^2-18x+4

So, Option C is correct.

13.33%

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
