Answer:
Cost for 35 songs: 1(35)+11=46
Cost for s songs: 1s+11
Step-by-step explanation:
The original are would be 48.
Since we know that the length and width are two consecutive even integers, we can model them as follows:
Width = x
Length = x + 2
This works because no matter what even number is put in for x, the length will also be even.
Now we know if we subtract 3 from the width, we have a new rectangle that gives us an area of 24 inches. Therefore, our new triangle has the following:
Width: x - 3
Length: x + 2
Area: 24
And we can plug this into the equation.
Length* Width = Area
(x + 2)(x - 3) = 24
x^2 - x - 6 = 24
x^2 - x - 30 = 0
This is not a quadratic that we can factor to show the following:
(x - 6)(x + 5) = 0
This gives us the answers of x = 6 and x = -5. Since a side can't be negative, we throw out the x = -5 and the answer is x = 6.
So if we go back to the original rectangle, we know:
Width = x = 6
Length = x + 2 = 8
Area = 6*8 = 48
Answer:
Step-by-step explanation:
Definition : The expression that can have constants (like 4), variables (like x or y) and exponents (like the 2 in
), that can be combined using addition, subtraction, multiplication and division, but no division by a variable and a variable's exponents can only be 0,1,2,3,... etc. and it can't have an infinite number of terms.
1. 6 + p
Being p be a variable this equation is polynomial
2. x – 1
Since x-1 has variable and constant so according to definition it is a polynomial
3. 8x−z3
According to definition it is a polynomial
4 .
Since has root so it is not a polynomial .
