To answer the question, we need to know what polynomials are
What are polynomials?Polynomials are algebraic expressions that contains variables and coefficients.
a.
2 - x² + 4x + x² = 2 - x² + x² + 4x
= 2 - 0 + 4x
= 2 + 4x
Since it has two terms, it is a binomial
b.
x - 5x² + 3 - 2 = x - 5x² + 1

Since it has three terms, it is a trinomial
c.
x² - x² + x² - x² + 3 = 0 + 0 + 3
= 3.
Since this contains a single term, it is a monomial
d.
7x - x² + x³ + 4x² = x³ + 4x² - x² + 7x
= x³ + 3x² + 7x
Since it has three terms, it is a trinomial

A water slide starts at (0,144) and ends at (12,0) what is the slope of the slide
Answer:
-12
Step-by-step explanation:
The slope of a line is just the difference of y-values divided by the difference of x-values
[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{144-0}{0-12} = \frac{144}{-12} = -12[/tex]

A unicorn daycare center requires there to be 2 supervisors for every 18 baby unicorns. Write an equation that shows the relationship between nnn, the number of supervisors, and uuu, the number of baby unicorns. Please note that this is a magical daycare center, so fractional supervisors are allowed.
Answer:
n = (1/9)u
Step-by-step explanation:
This is a direct variation relationship of the form
n = ku
For n = 2, u = 18.
2 = k * 18
We solve for k.
k = 2/18
k = 1/9
Now we use k in the equation of the relationship.
n = (1/9)u
All the fudge machines at a chocolate factory work at the same rate. Six machines working simultaneously can complete a big order in 22 hours. How many hours would it take to fill the order if the number of working machines decreased by factor of 4?
Answer:
88 hours
Step-by-step explanation:
Since we are decreasing the number of machines by a factor of four and all the machines work at the same rate, we are simply going to increase the work hours by a factor of 4
Increasing the work hours by a factor of 4 will yield 22 * 4 = 88 hours
So it will take 88 hours to fill the order if the number of machines is deceased by a factor of 4

Find a solution to the system. Make sure to write as a coordinate.
Answer:
x=2, y=3
Step-by-step explanation:
This is a system of equations.
To solve a system of equations, we use the substitution method.
We can plug in the first equation, [tex]x=2y-4[/tex], into the value for x in the second equation. Now, the second equation looks like this:
[tex]2*(2y-4)+y=7[/tex]
We simplify and solve for y:
→ [tex]4y-8+y=7[/tex]
→ [tex]5y=15[/tex]
→ [tex]y=3[/tex]
Now, we plug in the value for y, which is 3, into either equation. I will just use the first equation:
→ [tex]x=2*3-4[/tex]
→ [tex]x = 2[/tex]

If you look at the x, in this case -7, and follow it down to where it stops on the parabola, you will see that it's y value is -4.
230% of what number is 92
Answer:
250
Step-by-step explanation:
Following shows the steps on how to derive this formula
Step 1: If 92% of a number is 230, then what is 100% of that number? Setup the equation.
230
92% = Y
100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
92Y = 230 x 100
92Y = 23000

ABC is a central angke in a cirvle with center B. The length of the radius is 13 km and m
Answer:
[tex]\frac{1170pi}{360m}[/tex]km
Step-by-step explanation:
To find the length of the minor arc, you find the circumference of the circle multiplied by the arc angle, which is [tex]\frac{45}{m}[/tex] over 360 degrees.
Circumference of the circle with center B = 13×2×pi
= 26pi
Length of minor arc = 26pi × [tex]\frac{45}{m}[/tex] ×[tex]\frac{1}{360}[/tex]
= [tex]\frac{1170pi}{360m}[/tex]km
the distance between two towns is 300 km two cars start simultaneously from this towns and move towards each other the speed of one car is more than the other by 7 km per hour if the distance between the cars after 2 hours is 34 kilometre find the speed of the cars
Answer: I think its 131.19, but not too sure.
Step-by-step explanation:
To find the speed, you would do distance/time, so I added 300 and 7. I got 307, then I divided 307 (distance) from 2.34 (time). I got 131.19
Do you want the speed of both cars? then the answer would be:
(300)- first car= 128.20
(307)- second car= 131.19 (if you need to round this answer, it would be 131.2)

stidents who play basketball = 4y^2 + y - 8 - (2y + 16) = 4y^2 - y - 24
This is a question on forming and solving equations and expressions. If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)
Answer: Choice (b) 4y^2 - y - 24; top right corner
===========================================================
Work Shown:
T = total number of students in the class
T = 4y^2 + y - 8
F = number of students who play football
F = 2y+16
B = number of students who play basketball
B = unknown for now
Since a student either plays football or basketball, but not both, this means
T = F+B
which rearranges to
B = T-F
Plug in the given expressions and simplify
B = T-F
B = (4y^2+y-8) - (2y+16)
B = 4y^2+y-8 - 2y - 16
B = 4y^2 + (y-2y) + (-8-16)
B = 4y^2 - y - 24
