Two opposite sides of the parallelogram have lengths (5n − 6) cm and (3n − 2) cm. The third side measures (2n + 3) cm. What are the lengths of two adjacent sides of the parallelogram? 2 cm and 2 cm 4 cm and 7 cm 7 cm and 9 cm 13 cm and 19 cm
Answer:
Correct option is 2. The lengths of two adjacent sides of the parallelogram are 4 cm and 7 cm.
Step-by-step explanation:
The opposite sides of a parallelogram are equal.
[tex]5n-6=3n-2[/tex]
[tex]2n=4[/tex]
Divide both sides by 2.
[tex]n=2[/tex]
The value of n is 2.
The lengths of two adjacent sides of the parallelogram are
[tex]5n-6=5(2)-6=10-6=4[/tex]
[tex]2n+3=2(2)+3=7[/tex]
Therefore the correct option is 2. The lengths of two adjacent sides of the parallelogram are 4 cm and 7 cm.

The spiral in the picture is made from 45° right triangles. The smallest triangle (red) has a side length of 1. You can use the Pythagorean theorem to find the length of its hypotenuse. The next (orange) triangle has a side length exactly matching the hypotenuse of the smallest triangle, and so on with the larger triangles of other colors. The lengths of the hypotenuses of all the triangles (starting with the smallest) make a geometric sequence. What is the ratio of the sequence?
How many lateral faces does a pentagonal prism have? Explain its actually 8 for anyone who needs this in the future
A pentagonal prism has five lateral faces.
A pentagonal prism is a three-dimensional geometric figure with two parallel pentagonal bases and rectangular lateral faces. To determine the number of lateral faces:
(1) Visualize the pentagonal bases; a pentagon has five sides.
(2) Each side of the pentagon is perpendicular to a corresponding rectangle, forming a lateral face.
So, a pentagonal prism has five lateral faces, matching the number of sides of its base pentagon.
An octahedron, a completely different shape, has eight triangular faces, not to be confused with the prism.

A treasure chest lies 100 meters below sea level. Write a positive or negative integer that represents the situation.
An integer that represents the situation is -100.
What are integers?
Any positive or negative number without fractions or decimal places is known as an integer, often known as a "round number" or "whole number."
Integers are positive and negative whole numbers.
In this case, we are given a situation where a treasure chest is located 100 meters below sea level.
The sea level can be considered as zero, so anything below sea level would be negative.
Therefore, we use a negative integer to represent this situation, and the negative integer that represents 100 meters below sea level is -100.

Find constants a and b such that the function y = a sin(x) + b cos(x) satisfies the differential equation y'' + y' − 7y = sin(x).
The constants a = 1 and b = 1 satisfy the differential equation y'' + y' - 7y = sin(x).
Explanation:We can find the constants a and b by comparing the coefficients of the trigonometric functions in the given differential equation with the functions in the function y = a sin(x) + b cos(x).
In the differential equation, the coefficient of y'' is 1, the coefficient of y' is 1, and the coefficient of y is -7. In the function y = a sin(x) + b cos(x), the coefficient of sin(x) is a and the coefficient of cos(x) is b.
So, we equate the coefficients:
1 = a1 = b-7 = 0 (from the term -7y in the differential equation)Therefore, the constants a = 1 and b = 1 satisfy the differential equation.

The value of a is [tex]\frac{-8}{\ 65}[/tex] and value of b is [tex]\frac{-1}{\ 65}[/tex].
Given the function (y = a sin(x) + b cos(x)), we need to find constants a and b such that the function satisfies the differential equation:[tex]\frac{-1}{\ 65}[/tex]
y'' + y' − 7y = sin(x)
First, find the first derivative y':
y' = a cos(x) - b sin(x)
Next, find the second derivative y'':
y'' = -a sin(x) - b cos(x)
Substitute y, y', and y'' into the differential equation:
(-a sin(x) - b cos(x)) + (a cos(x) - b sin(x)) − 7(a sin(x) + b cos(x)) = sin(x)
Combine like terms:
(-a − 7a)sin(x) + (a cos(x)) + (-b - 7b)cos(x) - b sin(x) = sin(x)
Simplify the equation:
-8a sin(x) + a cos(x) + (-8b cos(x)) - b sin(x) = sin(x)
Separate the equation into two parts, one for sin(x) and one for cos(x):
(-8a - b)sin(x) + (a - 8b)cos(x) = sin(x)
Match coefficients to make equal:
-8a - b = 1a - 8b = 0Solve the system of equations:
From a - 8b = 0, we get a = 8bSubstitute a = 8b into -8a - b = 1:-8(8b) - b = 1 -64b - b = 1-65b = 1[tex]b = \frac{-1}{\ 65}[/tex]Then a = 8b[tex]a = 8(\frac{-1}{\ 65})[/tex]The constants are [tex]a = \frac{-8}{\ 65}[/tex] and [tex]b = \frac{-1}{\ 65}[/tex].
