Answer:
The result is 0.36b
Step-by-step explanation:
Here. we want to translate the wordings into an expression of algebra.
Firstly, we decrease b by 40%
40% is same as 40/100 = 0.4
So decreasing b by 40% = b-0.4(b) = b-0.4b = 0.6b
Now we want to decrease 0.6b by another 40%
= 0.6b -0.4(0.6b)
= 0.6b - 0.24b
= 0.36b
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>
Area of the rectangle is given as = 16 square inches
We know
Length * width = Area
Then
Width = Area/Length
Now
Perimeter = 2 (Length + Width)
Perimeter = 2[ {Length + (Area/Length)}]
Perimeter = 2[Length + (16/Length)]
When d(Perimeter)/d(length) = 0,
Then
2[Length + (16/Length)] = 0
Length + (16/Length) = 0
Length^2 + 16 = 0
(Length)^2 = -(4)^2
Then
Length = 4 inches
Now
Width = Area/Length
= 16/4
= 4 inches.
