To divide rational numbers, you turn the division problem into a multiplication problem by flipping the second rational number. Then you go ahead and multiply the tops and bottoms together to get your answer. If you can simplify your problem before multiplication, you can go ahead and do so to make your problem easier.
Answer:
√(3x)-2y+7
here √(3x) means, √3×√x
√x = x^(1/2)
now, now the exponent is 1/2, which means it's not a polynomial
Answer:

Step-by-step explanation:
Let x be the number of miles Jan can drive in a taxi.
The cost of this ride consists of
- $5.00 flat rate
- $.065 per mile
So, per x miles Jan will pay $0.65x and the total cost of the ride will be
$5.00+$0.65x
Jan has no more than $20 to spend on a ride, then the total cost of his ride must be less or equal to $20. Mathematically, you can write this as

-2. All you’re doing is going from the number you start with and performing the opperations in the order they appear (-4+3-2+6-5=-2)
