Find the perimeter of a rectangle in simplest expression form that has an area of
12x² - 11x - 5. Please make sure you show all your work for full credit.
=======================================================
Explanation:
I'll use the quadratic formula to find the roots or x intercepts. This slight detour allows us to factor without having to use guess-and-check methods.
The equation is of the form ax^2+bx+c = 0
a = 12b = -11c = -5This leads to...
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(-11)\pm\sqrt{(-11)^2-4(12)(-5)}}{2(12)}\\\\x = \frac{11\pm\sqrt{361}}{24}\\\\x = \frac{11\pm19}{24}\\\\x = \frac{11+19}{24} \ \text{ or } \ x = \frac{11-19}{24}\\\\x = \frac{30}{24} \ \text{ or } \ x = \frac{-8}{24}\\\\x = \frac{5}{4} \ \text{ or } \ x = -\frac{1}{3}[/tex]
Now use those roots to form these steps
[tex]x = \frac{5}{4} \ \text{ or } \ x = -\frac{1}{3}\\\\4x = 5 \ \text{ or } \ 3x = -1\\\\4x - 5 =0 \ \text{ or } \ 3x+1 = 0\\\\(4x-5)(3x+1) = 0[/tex]
Refer to the zero product property for more info.
Therefore, the original expression factors fully to (4x-5)(3x+1)
Use the FOIL rule to expand it out and you should get 12x^2-11x-5 again.
----------------------------------------------
We did that factoring so we could find the side lengths of the rectangle.
I'm using the fact that area = length*width
L = length = 4x-5W = width = 3x+1The order of length and width doesn't matter.
From here, we can then compute the perimeter of the rectangle
P = 2(L+W)
P = 2(4x-5+3x+1)
P = 2(7x-4)
P = 14x - 8

Factor completely 4h2 g. H(4h g) g(4h2) Prime gh(4h 1).
The expression can be divided by one and itself only. Then the expression is a prime expression. The correct option is C.
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The expression is [tex]\rm 4h^2 + g[/tex]
The expression can be written as
[tex]\rm (2h)^2 + g[/tex]
The expression can not be the real factor.
Since the expression can be divided by one and itself only.
Then the expression is a prime expression.
Thus, the correct option is C.

find the area of a circle with a radius of 7 feet. use 3.14 π
Answer:
153.86 ft²
Step-by-step explanation:
Formula to find the area of a circle is :
Area = πr²Here,
r ⇒ radius ⇒ 7 ft
Let us solve now.
A = π r²
= 3.14 × 7 × 7
= 21.98 × 7
= 153.86 ft²
Given :
radius of circle = 7 feetπ = 3.14[tex] \\ \\ [/tex]
To find :
Area of circle[tex] \\ \\ [/tex]
We know :-
[tex] \bigstar \boxed{ \rm Area~of \: a~circle = \pi {r}^{2} }[/tex]

Answer:
AC ≈ 7.8 units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = A (- 4, - 4 ) and (x₂, y₂ ) = C (2, 1 )

Monique is planning the locations for three exhibit areas at the festival. She drew a model of one of the exhibit areas as shown on the coordinate grid below. To determine the location of the second exhibit area, she will reflect the first area across the dashed line. To determine the location of the third exhibit area, she will translate the second area (x,y)→(x+1,y+6)
The second area was translated 1 unit right and 6 units down to form the third exhibit area.
TransformationTransformation is the movement of a point from its initial location to a new location. Types of transformation are translation, reflection, dilation and rotation.
Translation is the movement of a point either up, down, left or right.
Given the translation (x,y)→(x+1,y+6). Hence:
The second area was translated 1 unit right and 6 units down to form the third exhibit area.

I got this by: "d is 17 less than the quotient of n and 4"
d = n/4 - 17
So what we know is that there is a fraction (division) so I went ahead and made that. Then it says that it is 17 less than the quotient of n and 4, which means subtraction. Set it equal to d because that is the one we were trying to "solve" since the begging.
You have to find f(5)
Answer:
f(5) = -2
Step-by-step explanation:
Hello! So, when we have f(5), that is in the form of f(x). That means that our x = 5. Another thing to note is that f(x) is equivalent to our y-coordinate: the x-coordinate is the x value in the equation and the value is the f(x) in the equation.
Now we need to locate where x = 5 on the graph. When you find that, you need to see what point falls on x = 5. That points y-coordinate is your answer.
So if we look at x=5, the point (5, -2) falls on it. So f(5) = -2.

The Smith family wants to build an addition to the back of their house as shown in the figure below. The area of the addition is (x²+10x-200) ft².
a) What is the length of the addition?
b) What is the area of the original house?
The area of the house is the amount of space on the house.
The length of the addition is x + 20The area of the original house is [tex]x^2 + 30x + 200[/tex]The length of the additionThe area of the addition is given as:
[tex]Area = x^2 + 10x - 200[/tex]
Expand
[tex]Area = x^2 + 20x - 10x - 200[/tex]
Factorize
[tex]Area = x(x + 20) - 10(x + 20)[/tex]
Factor out x + 20
[tex]Area = (x -10)(x + 20)[/tex]
The width of the addition is x - 10.
Hence, the length of the addition is x + 20
The area of the original houseThe dimension of the original house is
x + 20 by x + 10
So, the area is:
[tex]Area =(x + 20)(x + 10)[/tex]
Expand
[tex]Area =x^2 + 20x + 10x + 200[/tex]
This gives
[tex]Area =x^2 + 30x + 200[/tex]
Hence, the area of the original house is [tex]x^2 + 30x + 200[/tex]

Which of the following is NOT a solution of the inequality y<-1
Hello.
y<-1
The sign "<" means "less than"
The solutions of the inequality are less than -1.
For example, -2 is a solution of the inequality (it makes the inequality true)
The numbers that don't make the inequality true are greater than -1.
For example, let's take 3.
3 is greater than -1.
Plug it into the inequality:
3<-1
As we can see, we have a false statement.

Cost of 5kg of wheat is Rs. 91.50. What quantity of wheat can be purchased in Rs. 183? (Topic- Ration and Proportion)
The ratio between the weight of the wheat and the cost is 5:(91.50)
When multiplying both quantity by a same number, it is an equivalent ratio.
(Also call the quantity of wheat that can be purchased as x)
5:(91.50) = x:183
(5x2):(91.50x2) = x:183
10 : 183 = x : 183
-> x = 10
So, the quantity of wheat that can be purchased in Rs. 183 is 10kg.
