Given:
Perimeter of a square = [tex]32x-12.8[/tex]
To find:
The side length of the square.
Solution:
We know that, the perimeter of the square is 4 times of its side length.
[tex]P=4a[/tex]
Where, a is the side length.
Perimeter of a square = [tex]32x-12.8[/tex]
Now,
[tex]4a=32x-12.8[/tex]
Divide both sides by 4.
[tex]a=\dfrac{32x-12.8}{4}[/tex]
[tex]a=\dfrac{32x}{4}-\dfrac{12.8}{4}[/tex]
[tex]a=8x-3.2[/tex]
Therefore, the side length of the square is [tex]8x-3.2[/tex] units.

What answer choice is the correct one
Answer:
A
Step-by-step explanation:
The answer is a because it goes below the x line into - X because its only 90° but doesn't cross into the - y, I don't know how to explain it better but I hope this helped!
Graph the line that represents a proportional relationship between y and x where the unit rate of change of y with respect to x is 4/5. In other words, a change of 1 unit in x corresponds to change of 4/5 units in y. Graph the line and write the equation of the line.
Answer:
The required line is will be:
y = 4/5xThe graph of the line y = 4/5x is attached below.
Step-by-step explanation:
We know that when y varies directly with x, we get the equation
y ∝ x
y = kx
k = y/x
where k is called the 'constant of variation'.
It is also clear that 'constant of variation' basically represents the slope m or rate of change, with the lines passing through the origin, so
given
k = 4/5
substitute k = 4/5 in the equation y = kx
y = kx
y = 4/5x
Therefore, the required line is will be:
y = 4/5xThe graph of the line y = 4/5x is attached below.
Which triangle is congruent to triangle GHK?
Answer:
C
Step-by-step explanation:
Answer:
The fourth one
Step-by-step explanation:
We know that every angle in a triangle has to add up to 180°. On triangle C, it has two measurements: 120° and 36°. Add them and get 166°. When you take 180° and subtract 156°, you get 24°, which is in the original triangle. So they are congruent.
Find the zero of the function below:
f(x) = 4x + 12
Answer:
x = - 3
Step-by-step explanation:
To find the zero, let f(x) = 0, that is
4x + 12 = 0 ( subtract 12 from both sides )
4x = - 12 ( divide both sides by 4 )
x = - 3 ← is the zero

please help me on this question
Answer:
3x + 4y = - 20
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - [tex]\frac{3}{4}[/tex] , thus
y = - [tex]\frac{3}{4}[/tex] x + c ← is the partial equation
To find c substitute (- 8, 1) into the partial equation
1 = 6 + c ⇒ c = 1 - 6 = - 5
y = - [tex]\frac{3}{4}[/tex] x - 5 ← in slope- intercept form
Multiply through by 4 to clear the fraction
4y = - 3x - 20 ( add 3x to both sides )
3x + 4y = - 20 ← in standard form

The point C(2,3) is translated along a vector that is parallel to the line y=3x-2. The translation vector has magnitude square root of 10. What are the possible images of point C? Fill in as many answers as possible.
Step-by-step explanation:
The translation vector v can be resolved into its x and y components, where x² + y² = 10 (Pythagoras' Theorem) and y = 3x
(parallel to y = 3x - 2, slope = 3).
We have x² + (3x)² = 10,
=> x² + 9x² = 10, 10x² = 10, x = 1 or x = -1.
When x = 1, y = 3. When x = -1, y = -3.
Therefore 2 possible translation vectors
are (1, 3) or (-1, -3).
First new C' = (2 + (1), 3 + (3)) = (3, 6).
Second new C'= (2 + (-1), 3 + (-3)) = (1, 0).
The possible images are (3, 6) and (1, 0).

Step-by-step explanation:
what is the LCM of 36 and 8
72 is the lcm because a LCM means The Least Common Multiple
Which term can be used in the blank of 36x3−22x2−__ so the greatest common factor of the resulting polynomial is 2x? Select two options.
2
4xy
12x
24
44y
Answer:
4xy and 12x
Step-by-step explanation:
In this question, we must select which of the options to put into the blank space that will make the polynomial 2x the biggest common factor. We have two choices to choose from.
Now, looking at the blank space, we should understand that any response we are going to choose is an answer that contains x next to the number.
That puts 24 and 44 years out of the way.
Let's take a look at 4xy and 12x now. Let's place them within the blank space;
36x^3-22x^2 - 4xy: 2x(18x^2-11x-2y) 2x(18x^2-11x-2y)
36x^3-22x^2-12x= 2x(18x^2-11x-6) and 36x^3-22x^2-12x
The explanation why we're not going to use 44y and 24 is that 2x is not a consideration either.

What is the simplified form of this expression??
Answer:
-(7 x^2 - 3 x - 5) thus A.
Step-by-step explanation:
Simplify the following:
-(4 x^2 - 2 x) - 3 x^2 + x + 5
Hint: | Factor common terms out of 4 x^2 - 2 x.
Factor 2 x out of 4 x^2 - 2 x:
-3 x^2 + x + 5 - 2 x (2 x - 1)
Hint: | Distribute -2 x over 2 x - 1.
-2 x (2 x - 1) = 2 x - 4 x^2:
2 x - 4 x^2 - 3 x^2 + x + 5
Hint: | Group like terms in -3 x^2 - 4 x^2 + 2 x + x + 5.
Grouping like terms, -3 x^2 - 4 x^2 + 2 x + x + 5 = (-3 x^2 - 4 x^2) + (x + 2 x) + 5:
(-3 x^2 - 4 x^2) + (x + 2 x) + 5
Hint: | Combine like terms in -3 x^2 - 4 x^2.
-3 x^2 - 4 x^2 = -7 x^2:
-7 x^2 + (x + 2 x) + 5
Hint: | Add like terms in x + 2 x.
x + 2 x = 3 x:
-7 x^2 + 3 x + 5
Hint: | Factor a minus sign out of -7 x^2 + 3 x + 5.
Factor -1 out of -7 x^2 + 3 x + 5:
Answer: -(7 x^2 - 3 x - 5)

trainers cost $60
The exchange rate is $1 = £0.749
Rehan says,
“The trainers cost less than £40”
Rehan is wrong.
Using a suitable approximation, show working to explain why.
Answer:
60 x 0.749 = 44.94
£44.94 > £40

the height of an object thrown vertically is given by s=-16t^2+100t+200. Height is meter and time is n seconds.
Answer:
456.25m
Step-by-step explanation:
Since the question did not ask for what to find, we can as well look for the maximum height reached by the object
Given the height of an object thrown vertically expressed as;
s=-16t^2+100t+200.
At max height,
dS/dt = 0
-32t+100 = 0
-32t = -100
t = 100/32
t = 3.125s
Get the Max height
s(3.125) = -16(3.125)²+100(3.125)+200
s(3.125) = -156.25+312.5+200
s(3.125) = 456.25m
Hence the maximum height reached by the object is 456.25m
d/4 > 5
solve for the variable
The answer is d > 20

At a small college of the students live on campus. There are 14 students in a Biology class. What is the probability that 10 of the students live on campus ? {Express answer as a percentage , round answer to the nearest tenth)
Answer:
10/14
Step-by-step explanation:
Step-by-step explanation:
Probability = No. of students living in campus/Students in biology class
= 10/14= 5/7
=>5/7 into % = (5/7)×100=71.428%
Now round the answer to the nearest tenth
=> 71.428%=71%
Hope this helps you.
