Answer:
length = 22 incheswidth = 8 inchesStep-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
Perimeter = 60 in
The statement
the length of a rectangle is 6 inches more than twice it's width is written as
l = 6 + 2w
Substitute the statement into the above formula
That's
60 = 2( 6 + 2w) + 2w
60 = 12 + 4w + 2w
6w = 60 - 12
6w = 48
Divide both sides by 6
w = 8
Substitute w = 6 into l = 6 + 2w
That's
l = 6 + 2(8)
l = 6 + 16
l = 22
The dimensions are
length = 22 inches
width = 8 inches
Hope this helps you

4y-x=6 solve the equation for x
Answer:
x=6
Step-by-step explanation:
you have to find the y value which should be 3 then subtract the x value. Which should be 6
Can someone please assist me with this? If so praise God :)
Answer:
option 1
Step-by-step explanation:
the square root of 6 is 2.44949, rounded it's 2.4
the square root of 42 is 6.48074, rounded it's 6.5
in option 1 the 6 is placed after the 2 because it is point 4, not quite 2 but a bit bigger than 2 but less than 3.
same thing for 42, it is placed after 6 because it is not quite 6 but not over 7. i hope this helped

Help please 50 points!
Answer:
84%
Step-by-step explanation:
The mean has 50% below the mean and 50 % above the mean
The mean is 103.47
The standard deviation is 4.07
Add the mean and the standard deviation
103.47+4.07 = 107.54
We want to know how much data is below the mean plus one standard deviation
Within one standard deviation is 68% , but that is on both sides, we are only needed on the right side so we need 1/2 of the 68 = 34
50+34 = 84

[tex]-2 ( x + 3) = -2 (x + 1) -4 \\-2x + 3 = -2x -2 -4\\-2x + 3 = -2x - 6[/tex]
add [tex]2x[/tex] to both sides
[tex]-2x + 3 + 2x = -2x - 6 + 2x \\3 = -6[/tex]
That's impossible

Answer:
All real numbers ( -∞ ,∞)
Step-by-step explanation:
Simplify [tex]-2(x+3)[/tex]
Apply the distributive property.
[tex]-2x-6=-2(x+1)-4[/tex]
Simplify
[tex]-2(x+1)-4[/tex]
[tex]-2x-6=-2x -6[/tex]
Move all terms containing x to the left side of the equation.
Add 2 x to both sides of the equation.
[tex]-2x-6+2x=0[/tex]
Combine the opposite terms in
[tex]-2x-6+2x[/tex]
add [tex]-2x[/tex] and [tex]2x[/tex]
[tex]0-6= -6[/tex]
[tex]-6= -6[/tex]
Since [tex]-6= -6[/tex] , the equation will always be true for any value of x . All real numbers
The result can be shown in multiple forms.

Given f(x) = 2x2 – 1 and g(x) = x + 3, find f(g(-5))
Answer:
7
Step-by-step explanation:
f(x) = 2x2 – 1 and g(x) = x + 3,
f(g(-5))
First find g(-5)
g(-5) = -5 + 3
g(-5) = -2
Then substitute into f(x)
f(-2) = 2 ( -2) ^2 -1
= 2 ( 4) -1
= 8-1
= 7
f(x)=2x -7, What is x when f(x)=-15?
Answer:
x = -4
Step-by-step explanation:
Plug in -15 into the equation:
f(x) = 2x - 7
-15 = 2x - 7
Solve for x:
-15 = 2x - 7
-8 = 2x
-4 = x

la cancha de futbol del colegio es de forma rectangular, pedro es el cargado de colocar un lazo alrededor para que nadie entre ala cancha si el ladao largo mide 100 mertros y el lado mas corto mide 64 metros ¿ cuanto debe medir el lazo
Answer:
328 metros
Step-by-step explanation:
Aquí, estamos interesados en colocar un bucle alrededor de un campo de fútbol de la escuela de manera que sea imposible que alguien pueda acceder al campo.
Matemáticamente, la longitud de este bucle sería igual al perímetro del campo.
El perímetro del campo rectangular se puede calcular usando la fórmula; 2 (L + B)
En este caso tenemos; P = 2 (100 + 64)
P = 2 (164)
P = 328 metros La longitud del bucle es de 328 metros.
Simplify by combining like terms.

Given f(x)=x−1−−−−√+2, what is the relationship between f(x) and f−1(x)? Drag and drop an inequality into each box to correctly complete each statement.
Answer:
The domain of f(x) is x>-2, so the range of f-1(x) is y>-2
The range of f(x) is y>-1, so the domain of the f-1(x) is x>-1
Step-by-step explanation:
To solve this question, we need to know the definition of domain and range.
The domain of a function is defined as all the possible input x-values while the range is defined as all the possible output y-values.
For f(x), domain for x is; x ≥ 1 and range is; y ≥ 2
For f⁻¹(x); domain is; x ≥ 2 and range is; x ≥ 1
We are given the function;
f(x) = [tex](\sqrt{x - 1} ) + 2[/tex]
Now, when x = 1, we will have zero inside the square root sign and this means that any x-value less than 1 will make the value inside the square root symbol to be negative which will result in an imaginary root.
Thus, we can say that, the domain for x is; x ≥ 1
Putting x = 1, we can find the least range value;
f(x) = 0 + 2
f(x) = 2
Thus, the range will be; y ≥ 2
Now, we want to find the range of f⁻¹(x)
This means an inverse of the original equation.
Thus;
f⁻¹(x) = [tex](x - 2)^{2} + 1[/tex]
Let's put x = 2;
f⁻¹(x) = (2 -2)² + 1
f⁻¹(x) = 1
Since x=2 gives the bracket to be zero, it means the domain is; x ≥ 2 and range is; x ≥ 1

Does anyone know how to solve this?
Answer:
14.76
Step-by-step explanation:
First find the length of the diagonal across the bottom using the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
12^2+5^2 = c^2
144+25 = c^2
169 = c^2
Take the square root of each side
sqrt(169) = sqrt(c^2)
13 = c
Then find the length of the diagonal across the middle using the Pythagorean theorem
7^2 + c^2 = d^2
7^2 + 13^2 = d^2
49+ 169 = d^2
218 = d^2
Take the square root of each side
sqrt(218) = sqrt(d^2)
14.76482306 = d
