Determine whether each expression is a polynomial. If it is a polynomial, find the degree and determine whether it is a monomial, binomial, or trinomil. 3z−2 2x3+x−12 9b 9x−2
Given that:
The expressions are [tex]3z−2, 2x^3+x-12, 9b, 9x-2[/tex].
Solution:
Monomial : It contains single terms.
Binomial : It contains two terms.
Trinomial : It contains three terms.
Polynomial : It contains atleast one algebraic term.
Degree of polynomial : It is highest power of the variable.
[tex]3z-2[/tex] , here z is the variable. So, it is a polynomial with degree 1 and it is a binomial.
[tex]2x^3+x-12[/tex] , here x is the variable with highest power 3. So, it is a polynomial with degree 3 and it is a trinomial.
[tex]9b[/tex] , here b is a constant. So, it is not a polynomial and it is a monomial.
[tex]9x-2[/tex] , here x is the variable. So, it is a polynomial with degree 1 and it is a binomial.

The area of a rectangle is 136 square centimeters. The
rectangle is 8 centimeters wide how long is the rectangle
Answer:17
Step-by-step explanation: count 8, 17 times and that is how you get your answer
The length of the rectangle is 17 cm if the area of a rectangle is 136 square centimeters.
What is the area of the rectangle?It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.
It is given that:
The area of a rectangle is 136 square centimeters.
A = 136 square cm
w = 8 cm
A = lw
136 = 8l
l = 17 cm
Thus, the length of the rectangle is 17 cm.

y ∝ 1 √ x If y = 5 when x = 49 find, y when x = 25
Answer:
y = 1/7
Step-by-step explanation:
y ∝ 1/√x ⇒ y = k/√xy = 5, x = 49 ⇒ 5 = k/√49 ⇒ 5 = 7k ⇒ k = 5/7y = 5/(7√x) ⇒ x = 25 ⇒ y = 5/(7√25) = 5/(7·5) = 1/7The value of x is 25 then y is 7.
What is Proportionality?In mathematics, proportionality denotes a linear relationship between two quantities or variables. Both quantities increase in size when one doubles, and both decrease in size when one drops to a tenth of its original value.
Given:
y ∝ 1 √ x
and, y= 5 when x= 49
So, the relation will be
y ∝ 1/√x
y = k/√x
So, 5 = k/√49
5 = k /7
k = 35
Now, k = y/ √x
35 = y √25
35 = 5y
y = 7
Hence, when x is 25 then y is 7.

My favorite group, The Lumineers, is coming to Prescott and YC for a concert. Tickets are sold in three levels, $45, $65, and $95 depending on seats. The auditorium seats 1100 people total on the different levels; for them to come to YC we need to sell $66,500 worth of tickets and the auditorium has as many cheap ($45) tickets as the sum of the other two levels ($65 and $95).
Answer:
550 $45 tickets, so $24750 worth of $45 tickets
Step-by-step explanation:
If $45 tickets=x, $65=y, and $95=z, then the question is saying x=y+z. And if x+y+z=1,100, then x=1100/2, so 550 $45 tickets. 550*45 is $24750

Since C is between B and D , then
BC + CD = BD , substitute values
8x + 13 + 12x - 73 = 320 , that is
20x - 60 = 320 ( add 60 to both sides )
20x = 380 ( divide both sides by 20 )

4(2-4x)-3x=65 Whats the answer and how did you solve it?
Answer:
x= -3
Step-by-step explanation:
Distribute 4(2-4x) which leaves you with 8-16x-3x=65
combine the like terms which leaves you with 8-19x=65
subtract 8 from both sides 8-19x-8=65-8 which leaves you with -19x=57
lastly divide -19 from both sides which leaves you with x= -3
