the width of a rectangle is two feet less than the length. the perimeter is 52 feet. find the length and the width.
If the width of a rectangle is two feet less than the length and the perimeter is 52 feet, then the length and width of the rectangle is 14 feet and 12 feet respectively
The width of a rectangle is two feet less than the length
Consider the length of the rectangle as x
Then the width of the rectangle = x - 2
The perimeter of the rectangle = 52 feet
The perimeter of the rectangle = 2(l + w)
Where l is the length and w id the width
Substitute the values in the equation
2(x + x - 2) = 52
2(2x - 2) = 52
2x - 2 = 52/2
2x - 2 = 26
2x = 28
x = 14 feet
Width of the rectangle = 14 - 2
= 12 feet
Therefore, the length and width of the rectangle is 14 feet and 12 feet respectively

Solve the system using substitution or elimination:
8x - 3y = -13
-3x + 5y = 1
Make sure you answer is an ordered pair (x, y).
Answer:
{x = -2, y = -1
Step-by-step explanation:
Solve the following system:
{-3 y + 8 x = -13
5 y - 3 x = 1
Choose an equation and a variable to solve for.
In the first equation, look to solve for x:
{-3 y + 8 x = -13
5 y - 3 x = 1
Isolate terms with x to the left-hand side.
Add 3 y to both sides:
{8 x = 3 y - 13
5 y - 3 x = 1
Hint: | Solve for x.
Divide both sides by 8:
{x = (3 y)/8 - 13/8
5 y - 3 x = 1
Perform a substitution.
Substitute x = (3 y)/8 - 13/8 into the second equation:
{x = (3 y)/8 - 13/8
5 y - 3 ((3 y)/8 - 13/8) = 1
Expand the left-hand side of the equation 5 y - 3 ((3 y)/8 - 13/8) = 1.
5 y - 3 ((3 y)/8 - 13/8) = 5 y + (-(9 y)/8 + 39/8) = (31 y)/8 + 39/8:
{x = (3 y)/8 - 13/8
((31 y)/8 + 39/8) = 1
Choose an equation and a variable to solve for.
In the second equation, look to solve for y:
{x = (3 y)/8 - 13/8
(31 y)/8 + 39/8 = 1
Isolate terms with y to the left-hand side.
Subtract 39/8 from both sides:
{x = (3 y)/8 - 13/8
(31 y)/8 = -31/8
Solve for y.
Multiply both sides by 8/31:
{x = (3 y)/8 - 13/8
y = -1
Hint: | Perform a back substitution.
Substitute y = -1 into the first equation:
Answer: {x = -2, y = -1

What is meant by geometric mean theorem?The relationship between the height on the hypotenuse of a right triangle and the two line segments it generates on the hypotenuse is described by the right triangle altitude theorem, also known as the geometric mean theorem, which is a consequence of elementary geometry. It claims that the altitude is equal to the geometric mean of the two segments.The later version provides a method for squaring a rectangle using a ruler and compass, which entails creating a square with the same area as the rectangle in question.Since the inverse of Thales' theorem guarantees that the hypotenuse of the right angled triangle is the diameter of its circumcircle, the theorem may also be seen as a specific example of the intersecting chords theorem for a circle.Given data :
m∠XBC = m∠BAC + m∠BCA,
Now if : m∠XBC=(3p-6)°: m∠BAC=(p+4)°: m∠BCA=84°,
then we get the equation :
3p-6=p+4+84

Let A be the area of the curve so,
A = [tex]\int\limits^a_b {\frac{1}{2} r^2 } \, d\theta[/tex]
where a and b is the boundary at which r=0
so after equation r=0
sin(8θ) =0

You can represent the perimeter of a shape with the two expressions 6x - 8 and 4(1.5x - 2). What does 4(1.5x -2) tell you about the shape that 6x - 8 does not?
The expression 6x-8 represents the perimeter of a shape in terms of the length of one of its sides, while the expression 4(1.5x-2) represents the perimeter of the same shape in terms of the length of its diagonals. Therefore, the expression 4(1.5x-2) provides additional information about the shape that is not contained in the expression 6x-8. Specifically, the expression 4(1.5x-2) tells us that the length of each diagonal of the shape is equal to 1.5 times the length of one of its sides minus 2. This information allows us to determine the lengths of the diagonals of the shape, which is not possible with the information provided by the expression 6x-8.

What in mathematics is a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
y=mx+c; where y and x stand for the respective axis's; 'm' represents the slope while 'c' represents the constant.
Let the point through which the line passes be P
Then, P= (-6,5)
m= 2
The equation of a straight line as a single point form can be found using the formula:
y-y1=m(x-x1)+c
y-(5) = 2(x-(-6))+c
y -5= 2(x+ 6)+c
Taking LCM
y - 5 =2(x+6)

pls help asap i can’t pass this class without passing this test
To answer this question, we need to first multiply the left side of the given equation and write it as the difference of two squares. This can be done by using the difference of squares formula, which states that the difference of two squares can be written as the product of the square of the sum and the square of the difference.
The left side of the given equation can be written as:
(csc0+1)(csc0-1)
We can then apply the difference of squares formula to this expression to get:
(csc0+1)(csc0-1) = (csc0+1)(csc0-1)
Now, we can see that this expression is equivalent to cot 0 using the Pythagorean Identity. This identity states that the sum of the squares of the cosecant and cotangent of an angle is equal to 1. In this case, since (csc0+1)(csc0-1) = cot 0, we can use the Pythagorean Identity to rewrite the left side of the equation as (csc0^2 + cot0^2) = 1, which is equivalent to cot 0.
Therefore, the correct answer is C. Pythagorean Identity
