What is the completely factored form of this polynomial?
18x3 – 120x2 - 42x
Write the greatest common factor (GCF) first, and write all factors in standard form.
Answer:
6x(3x + 1)(x - 7)
Step-by-step explanation:
First look for the greatest common factor of the 3 terms.
The GCF is 6x, so
18x^3 – 120x^2 – 42x
= 6x(3x^2 - 20x - 7)
Now we look to factor the quadratic expression in the parentheses:
The first and last coefficients are multiplied
3 * -7 = -21.
We look for 2 numbers whose product is -21 and whose sum is -20:
They are -21 and + 1 , so we write:
6x(3x^2 - 21x + 1x - 7)
= 6x [ (3x(x - 7) + 1(x - 7)] Note that x - 7 is common, so:
= 6x(3x + 1)(x - 7) Answer

What is the smallest multiple of 18 of the form 2A945B, where A and B are digits?
Answer:
[tex]219456[/tex]
Step-by-step explanation:
It must end in [tex]0,2,4,6,8[/tex] (divisible by 2 rule) and the digits must sum to a multiple of 9(divisible by 9 rule).
The digit sum is [tex]2+A+9+4+5+B=20+A+B[/tex].
We want to make [tex]A[/tex] as low as possible because it's a higher digit than [tex]B[/tex].
If [tex]A[/tex] is as low as possible, we have that the sum is [tex]20+0+7=27[/tex]. Uh-oh. [tex]B[/tex] has to be even! So [tex]A=0[/tex] doesn't work.
If [tex]A=1[/tex], we have that the sum is [tex]20+1+6=27[/tex]. Yay!
So, the answer is [tex]\boxed{219456}[/tex]

A city planner wants to build a road parallel to 2nd Ave . What is the slope of the new road?
Answer:
0
Step-by-step explanation:
By inspection or finding points, we see that 2nd ave is perfectly flat, or in other words, has slope of 0.
If line 1 is parallel to line 2, it means their slopes are the same.
So, the new road parallel to 2nd ave has a slope of [tex]\boxed{0}[/tex].
point Find the length of segment CD with C(2,3) and D (-3, 15
Step-by-step explanation:
so, if the text is correct, the 2 points are
(2, 3) and (-3, 15).
the length of the line segment is the distance between both points.
did this we use Pythagoras for right-angled triangles.
c² = a² + b²
c is the Hypotenuse and the distance between both points. a and b are the legs (enclosing the 90 degree angle), which are simply the differences of the x and the y coordinates.
so,
distance² = (2 - -3)² + (3 - 15)² = 5² + (-12)² = 25 + 144 = 169
distance = sqrt(169) = 13 = length of line segment

Answer:
2nd answer, and 5 hours
Step-by-step explanation:
Section 1
The answer is the 2nd one down. The tickets are selling at a rate of
floor tickets: 100/h; stand tickets: 75/h
Since the stand tickets were selling 150 in 2 hours, only 75 were sold per hour.
Section 2
There are only 375 stand tickets left to sell.
Every 2 hours 150 are sold or you can also say 75 per hour.
If you're selling 75 per hour, you would divide 375 by 75 which would give you 5 hours to sell out the stands tickets.
375/75 = 5 hours

What are the three forms a solution can
written in?
Answer:
solid solutionliquid solutiongas solution3x+10=43 what is x to the what are the steps to equal X to the math equation
Answer:
x = 11
Step-by-step explanation:
When solving for x, you want to get the variable by itself on one side of the equation. The first step is to subtract 10 from both sides. 43-10=33. So, it should look like:
3x = 33
Divide both sides of the equation by 3 to get x alone. 33/3 equals 11. So x =11. Hope this helped and lmk if you have more questions!!

Graph the line that passes through the points (-5, 3) and (−1,−1) and determine the equation of the line.
A line can be drawn by joining the plot of the two given points
Please find attached the graph of the line created with MS ExcelThe equation of the line is y = -x - 2Reason:
Given points on the line are (-5, 3) and (-1, -1)
From the given points, the graph of the line can be plotted with MS ExcelThe slope, m, of the line is given as follows
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Therefore, we have;
[tex]Slope, \, m =\dfrac{-1 - 3}{-1 - (-5)} = \dfrac{-4}{4} = -1[/tex]
The equation of the line in point and slope form is therefore;
y - 3 = -1·(x - (-5) = -x - 5
In slope and intercept form, we have;
y = -x - 5 + 3 = -x - 2
The equation of the line in slope and intercept form is y = -x - 2Learn more here:

= 170/5
Combined weight
= 170/5 + 211/5

What value of x makes the equation -5x - (-7 - 4x) = -2(3x - 4) tru
Answer: 1/10 or 0.1
Step-by-step explanation:
-(-7 - 4x) = -2(3x - 4)
7 + 4x = -6x + 8
* subtract 7 from both sides
4x = -6x + 1
* Add 6x to both sides
10 x = 1
* Divide both sides by 10
x = 1/10 or 0.10

if you wrote the number 0.0009763 as a single digit times a power of ten, would the exponent be positive or negative? explain.
Answer:
10^n means to multiply by 10
10^-n means to divide by 10 or multiply by 1 / 10
So .0009763 means 9.763 / 10000 = 9.763 * 10-4
can also write as 9.763E-4
If multiplying then the power of 10 would have to be negative

Lin is paid $86 for 4 hours of work how much would she be paid at this rate for 9 hours of work?
Answer:
173.5
Step-by-step explanation:
The answer is 173.5
To solve this type of equation we first have to find the unit rate, in this case, the unit rate is dollars every hour, in order to find this we have to divide 86 by 4 as shown below
[tex]86/4=21.5[/tex]
Therefore the unit rate is 21.5$ every hour so in order to find how much money she was paid after 9 hours we have to multiply 21.5 by 9, which is shown below
[tex]9x21.5=173.5[/tex]
Thus, that is how much money Lin will be paid after 9 hours of work.

I need a equation written for this pleeeeeaaaassse! The constant of proportionality is 2.
but I need an equation for this, I have an attachment for you to help. g= c is not correct sorry.
It sounds like your teacher wants g = 2c as the answer. The constant of proportionality simply tells us what to multiply the input variable by, to get the output variable.
It's similar to saying y = 2x, but we use c in place of x and use g in place of y.
