First multiply everything inside the brackets by seven
7x^4-42+3
Then solve what you can
7x^4-39
You an't solve it further. Is this what you mean? X to the fourth power?
<em><u>The expressions that are polynomial are:</u></em>
6 + w

z + 1
<em><u>Solution:</u></em>
A polynomial is an expression with variables and coefficients with the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables
1) 6 + w
Here "w" is a variable, hence it is a polynomial expression

This is a polynomial, since it has variables and coefficients and variable with non negative exponent
3) z + 1
This is also a polynomial with variable "z" and has addition operation

Since it has root so it is not a polynomial
Ok, were starting at when the stock increased first which is 12 cents on monday. to find your answer your going to need to add all of the increased cents first; then subtract.
12 + 14 = 26
So we have 26 cents, now we subtract the 56.
26 - 56 = -30
now we have -30. now we find out how far away on the number line it is from 12. your answer would be 42.
now for your answer, (i did all of that for other people who had the same question but different answer)
your answer would be 112 cents (which is option B)
T in time in minutes would be 60 min every hour 35/.6 minutes
