Which polynomial is written in descending order? (2 points) select one: a. 9 − 3x + 4x2 b. −3x + 9 + 4x2 c. 4x2 − 3x + 9 d. 4x2 + 9 − 3x

Option C. (4x² -3x + 9)

Step-by-step explanation:

Arranging a polynomial in descending order means to arrange the powers of variables of each term in the descending order.

So in the given options only Option C. is in the descending order.

4x² - 3x + 9

This polynomial has the variable x² with maximum degree of 2 at the starting.

Then second variable 3x with degree of 1 and then constant term 9.

Option C. is the correct option.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
