Answer:
[tex]Perimeter = 22x - 14[/tex]
[tex]Area = 30 {x}^{2} - 38x + 12[/tex]
Step-by-step explanation:
Length of rectangle (l) = 5x - 3
Weidth of rectangle (w) = 6x - 4
Perimeter of the rectangle = [tex]2(l + w)[/tex]
[tex] = > 2(5x - 3 + 6x - 4)[/tex]
[tex] = > 2(11x - 7)[/tex]
[tex] = > 22x - 14[/tex]
Area of the rectangle = [tex]l \times w[/tex]
[tex] = > (5x - 3)(6x - 4)[/tex]
[tex] = > 5x(6x - 4) - 3(6x -4)[/tex]

Mac uses 3.5 liters of water with 4
lemons to make lemonade. How many
lemons are needed if Mac uses 7 liters of
water to make lemonade?
Answer:
if I'm correct, it should be 6.125. I'm sorry if I'm wrong,
Step-by-step explanation:
take 3.5 and divide it by 4, which gives you the amount for 1 lemon. times that by 7, and you get 6.125
Answer:
8 lemons
Step-by-step explanation:
7- 3.5= 3.5
Therefore we multiple 3.5 by 2.
We always do the same on the other side.
4 times 2 equals 8
7 liters of water: 8 lemons

8. If a runner’s power is 400 W as she runs, how much chemical energy does she convert into other forms in 10.0 minutes? E = P X t
Answer:
2400kJ
Step-by-step explanation:
Step one:
given data
power P= 400W
time = 10minutes
to seconds= 60*10 = 600 seconds
Required
the energy
Step two:
we know that Energy= power * time
E=P*t
E=400*600
E=240000
E=2400kJ
She converts 2400kJ into other forms
Using these coordinates, find the slope. (0, -6), (3, -2)
Answer:
The slope between the points (0, -6) and (3, -2) will be:
[tex]m=\frac{4}{3}[/tex]Step-by-step explanation:
Given the points
(0, -6)(3, -2)The slope between the points (0, -6) and (3, -2) will be:

The difference between two whole numbers is 9. Twice the smaller number is 6 more than the larger. What is the smaller number?
The smaller number is 15
let
the larger number = x
the smaller number = y
Therefore,
The difference between the two whole numbers is 9 can be express as follows:
x - y = 9Twice the smaller number is 6 more than the larger. Therefore,
2y = x + 6Combine the equation.
x - y = 9
-x + 2y = 6
y = 15
x - 15 = 9
x = 9 + 15
x = 24
Therefore,
The larger number = 24
The smaller number = 15

The first coordinate of the point ( - 3, 2) indicates the point is located
Answer:
In the first coordinate
Step-by-step explanation:
For x = -3, the point is either located in 2nd or 3rd quadrant.
What is the general equation of a Straight line? What is a coordinate?
The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
A coordinate is represented as -
P(x, y)
where -
[x] is abscissa
[y] is ordinate
We have the following coordinate -
(-3, 2)
For x = -3, the point is either located in 2nd or 3rd quadrant
Therefore, for x = -3, the point is either located in 2nd or 3rd quadrant.

x-10x+1< 20+ 5x for x = -2
Help me please
Answer:
As the x=-2 does not satisfy the inequality.
Therefore, the solution is False!
Step-by-step explanation:
Given the expression
[tex]x-10x+1<\:20+\:5x\:[/tex]
substituting the value x = -2
[tex]\left(-2\right)-10\left(-2\right)+1<20+5\left(-2\right)[/tex]
[tex]-2+20+1 < 20-10[/tex]

As the x=-2 does not satisfy the inequality.
Therefore, the solution is False!
The ratio of employees who own a red car to employees who own a black car is
1:5. If there are 6 employees who own a red car, how many employees own a
black car? *
Answer:
There would be 30 black cars.
Since the ratio is 1:5
And we know that there are 6 red cars,
we basically just input it in our ratio
so it would look like 6:x
Now, we just have to plug in for x.
To do that, you have to multiply 6 by 5
To match the ratio.
So that would give us 6:30
And if we divide by 5 we should get our original ratio.
I know this seems confusing haha, but I hope you get it, it's not as hard as it looks !!

Polynomial Remainder Theorem
The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-a) is equal to f(a).
As a consequence, if a polynomial is divisible by x-a, f(a)=0.
Part 1:
Let's make:
[tex]f(x)=(x+b)^3+(x+c)^2-(b-c)[/tex]
To find out if x+b is a factor of f(x), we find f(-b):
[tex]f(-b)=(-b+b)^3+(-b+c)^2-(b-c)[/tex]
Operating:
[tex]f(-b)=(-b+c)^2-(b-c)[/tex]
The value of f(-b) is not zero. This means Eunju is right, x+b is not a factor of f(x).
Part 2:
We must find out if [tex]x^2+5x+6[/tex] is a factor of [tex]x^4+5x^3+2x^2-20x-24[/tex] without using long division or synthetic division.
We can use the polynomial remainder theorem again, but since the factor is not in the form (x-a), we can factor it as follows:
[tex]x^2+5x+6 =(x+2)(x+3)[/tex]
Now we just apply the theorem twice. If both remainders are zero, then the assumption is true.
Let's make:
[tex]f(x)=x^4+5x^3+2x^2-20x-24[/tex]
Find f(-2):
[tex]f(-2)=(-2)^4+5(-2)^3+2(-2)^2-20(-2)-24[/tex]
[tex]f(-2)=16-5*8+2*4+40-24 =16-40+8+40-24=0[/tex]
Find f(-3):
[tex]f(-3)=(-3)^4+5(-3)^3+2(-3)^2-20(-3)-24[/tex]
[tex]f(-3)=81-5*27+2*9+60-24[/tex]
[tex]f(-3)=81-135+18+60-24 =0[/tex]
Since both f(-2) and f(-3) are zero, [tex]x^2+5x+6[/tex] is a factor of [tex]x^4+5x^3+2x^2-20x-24[/tex].
