A polynomial is written correctly when the exponents are listed in order from highest to lowest. The highest exponent then dictates the degree of the whole polynomial. The first choice above is written in standard form from highest degree to lowest. Doesn't matter that we might skip the x-squared term or any other x-term, as long as they're in order from highest to lowest. The degree on that first polynomial, the one you're after, is 4 because that's the highest exponent, and there are 4 terms there. Terms are "bunches" of numbers and variables stuck together by multiplication and separated by + or - signs.
Answer:

Step-by-step explanation:
Given
f(x) = 
Finding f(-1) means, we have to put -1 in the places of x in the function,
So, putting x=-1 in the function

As the power 3 is odd, the minus will remain the same, while in the 2nd term minus will be eliminated due to even power. So,
=> 
=> 1
Hence,

Answer:
True
Step-by-step explanation:
x=5+7=12
The only solution is x=12.
Let's set up a proportion.
36 x
___ ___
140 100
Solve for x
36 x 100 = 3600
3600/140 = about 26%
The answer is C. 26%
