To know which of the following expressions are polynomials, let us look at the definition of a polynomial:
Polynomial is derived from poly- (which means "many") and -nomial (meaning "term"), so it says "many terms".
For an instance: 
is a polynomial, but 
is not a polynomial because it contains single term only.
We must keep in mind that in polynomial it can have variables, constants, and exponents but it can never have division by a variable.
Now lets, look at the
since it has got one term it can not be a polynomial.
: it has got <em>more than one term</em> therefore, <em>it is a polynomial. </em>
: again it has got just one term so it is not a polynomial.
: Since it has got <em>more than one term</em>, so again<em> it is a polynomial. </em>
Answer:
Step-by-step explanation:
Interest formula -
I = P × R × T
I = 3,280 × 0.3% × 9
What I basically did there wws multiply the amount of money, the simple interest, and the time.
Turn 0.3% into a decimal by dividing by a 100 which should give you 0.003
I = 3,280 × 0.003 × 9
Put that into a calculator, you get $88.56
Now, that's just the interest amount. Now you add it back to 3,280 to get the *total* amount.
3,280 + 88.56 = 3,368.56
Cathy ends us paying $3,368.56
Hope what I said made sense.
$6.25 × h = c
h = hours, c = total cost
$31.25 for 5 hours. $6.25 per hour
$50 for 8 hours. $6.25 per hour
40/60 = 2/3 of the teachers are from Ireland.
Answer:
-11
Step-by-step explanation:
3x+10=2x-1
3x-2x+10=-1
x+10=-1
x=-1-10
x=-11
