What is the perimeter of a rectangle with a length of 3x-2 width 2x-8
Answer:
P = 5x - 10
Step-by-step explanation:
The perimeter is:
P = L + w
L = 3x - 2
w = 2x - 8
P = 3x -2 + 2x - 8
P = 5x - 10
To know the exact value we need to know the value of x or the solve of one of the expressions above.

Consider the line y=2/5-4/3x what is the slope of a line perpendicular to this line
The product of the slopes of this line and the line perpendicular to it is equal to -1.
Note that the slope if the coefficient of x.
Let
[tex] \alpha [/tex]
be the slope of the given line.
Let
[tex] \beta [/tex]
be the slope of the line perpendicular to it.
I can therefore say,
[tex] \alpha \times \beta = - 1[/tex]
[tex] \frac{ - 4}{3} \times \beta = - 1[/tex]
[tex] \beta = \frac{ - 1}{ \frac{ - 4}{3} } [/tex]
[tex] \beta = \frac{ - 3}{ - 4} = \frac{3}{ 4} [/tex]
The slope is 3/4
Democrat F39 M27 Republican F57 M36 What percentage of the total sample are female Democrats?
Answer: Approximately 24.53%
Explanation:
I could be misreading what you posted, but it appears there are 39 female Democrats out of 39+27+57+36 = 159 total people surveyed.
This leads to the percentage 39/159 = 0.2453 = 24.53% which is approximate.

Answer:
C. y = 1/8x
D. y = x - 133
Step-by-step explanation:
In order to find the answer, you have to think about the answer choices
A. is saying that if you multiply 152 by 8, you will get 19 which is definitely not true
B. is saying that y is equal to 152/133 which is not true since 152/133= 8/7 which is some wacky decimal
C. would make sense because if you divide 152 and 8, you will get 19
Which makes the equation true because if you multiply 1/8 by 152/1, you get 152/8 which simplifies to 19 which satisfies the equation
D. This would also make sense since 152-133=19
So at the end, we can come to a conclusion that:
C. and D. are the equations that satisfy the relation

Given :-
z = -1/4
Inputting the values :-
2/z + 3/z²
2/(-1/4) + 3/(-1/4)²
(2 x -4) + (3 x 16)
-8 + 48

[tex]\textsf{if} \ z=-\dfrac14[/tex]
[tex]\implies \dfrac{2}{-\frac14}+\dfrac{3}{(-\frac14)^2}[/tex]
[tex]\implies -\dfrac{2}{\frac14}+\dfrac{3}{\frac{1}{16}}[/tex]
[tex]\implies -2 \times 4+3 \times 16[/tex]
[tex]\implies -8+48[/tex]
[tex]\implies 40[/tex]

ABC and ADE are similar. Find the length of size CA
Answer:
since ABC and ADE are similar,they have equal areas.
(AC)^2/(AE)^2=area ABC/ADE
areaABC=ACE=1
so substitute it in the afformentioned equation
u will get,AC=AE
The length of side CA in triangle ABC is c * (a² + ab + ac) / (a * (a + b + c)).
To find the length of side CA in triangle ABC, we need to use the concept of similarity and corresponding sides. Let's denote the lengths of sides in each triangle:
Triangle ABC:
Length of side AB: a
Length of side BC: b
Length of side CA: c
Triangle ADE:
Length of side AD: x (corresponding to side AB in ABC)
Length of side DE: y (corresponding to side BC in ABC)
Length of side EA: z (corresponding to side CA in ABC)
Since triangles ABC and ADE are similar, their corresponding sides are in proportion:
AD/AB = DE/BC = EA/CA
We know that AD corresponds to AB, and DE corresponds to BC, so we can set up the following proportions:
x/a = y/b
Solving for y, we get:
y = (b * x) / a
Next, we can set up the proportion for EA/CA:
z/c = x/a
Solving for z, we get:
z = (c * x) / a
Now, we have expressions for y and z in terms of x, a, and b. Since the sum of the lengths of the sides of a triangle is always constant, we can write the equation:
x + y + z = a + b + c
Substituting the expressions for y and z:
x + (b * x) / a + (c * x) / a = a + b + c
To find the value of x, we can multiply the entire equation by a to eliminate the denominator:
a * x + b * x + c * x = a² + ab + ac
Combining the x terms:
x * (a + b + c) = a² + ab + ac
Dividing both sides by (a + b + c):
x = (a² + ab + ac) / (a + b + c)
Now that we have found the value of x, we can substitute it back into the expression for z:
z = (c * x) / a
z = (c * (a² + ab + ac) / (a + b + c)) / a
Simplifying:
z = c * (a² + ab + ac) / (a * (a + b + c))
Thus, we have found the length of side CA in triangle ABC:

What is the missing base of 9=____ to the power of 2?
Answer: 3
Step-by-step explanation:
Let x be the missing base. In this case, base to the power of 2 means this number x times itself will equal 9.
9 = [tex]x^{2}[/tex]
[tex]\sqrt{9}[/tex] = [tex]\sqrt{x^{2} }[/tex] [use square root to cancel the power of 2].
[tex]\sqrt{9}[/tex] = x

Which is a factor of the polynomial f(x) = 6x4 – 21x3 – 4x2 + 24x – 35?
2x – 7
2x + 7
3x – 7
3x + 7
Answer:
first option
Step-by-step explanation:
i just took the test on edge.
The factor of the polynomial [tex]f(x) = 6x^4 - 21x^3 - 4x^2 + 24x - 35[/tex] is (a) 2x - 7
The polynomial function is given as:
[tex]f(x) = 6x^4 - 21x^3 - 4x^2 + 24x - 35[/tex]
To determine if 2x - 7 is a factor, we start by setting it to 0
[tex]2x - 7 = 0[/tex]
Add 7 to both sides
[tex]2x = 7[/tex]
Divide both sides by 2
[tex]x =3.5[/tex]
Substitute 3.5 for x in f(x)
[tex]f(3.5) = 6(3.5)^4 - 21(3.5)^3 - 4(3.5)^2 + 24(3.5) - 35[/tex]
[tex]f(3.5) =0[/tex]
Because f(3.5) equals 0, then 2x - 7 is a factor of the polynomial

Find the rule to solve for N. X,5,6,n,10 Y,20,24,32,40
Answer:
Step-by-step explanation:
Consider what y values you are getting by letting x = 5 and then letting x = 6.
when x = 5 , y = 20
y = m*5
20 = m*5 Divide by 5
20/5 = m/5
4 = m
when x = 6 y = 24
y = mx
24 = m*6 Divide by 6
24/6 = m
m = 4
So now we can be sure of our solution for x when y = 32
y = m*n
32 = 4*n Divide both sides by 4
32/4 = 4*n/4
n = 8
Answer: n = 8
