The four sides of the quadrilateral are 9 m,10 m, 11 m and 12 m.
What is a quadrilateral?
A quadrilateral is a four-sided polygon with four angles and four vertices. The term "quadrilateral" comes from the Latin words "quadri," which means "four," and "latus," which means "side."
Let the four sides of the quadrilateral be (x-2), (x-1), x, (x+1).
Then, perimeter = (x-2) + (x-1) + x + (x+1)
i.e., x - 2 + x - 1 + x + x + 1 = 42
i.e., 4x - 2 = 42
i.e., 4x = 42 + 2
i.e., 4x = 44
i.e., x = 11
Hence, the four sides of the quadrilateral are 9 meters, 10 meters, 11 meters and 12 meters.

A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.
From the given information:
f(x)=x^3+6x^2+17x+14; slope of the tangent line=5
Then
f(x)=x^3+6x^2+17x+14
Now find the drivative then
f'(x)=3x^2+12x+17
Then slope of the tangent line=5
Now,
3x^2+12x+17 = 5
3x^2+12x+12 = 0
x^2+4x+4 = 0
Now solve the equation then
x^2+2x+2x+4 = 0
x(x+2) +2(x+2) = 0
(x+2) (x+2) = 0

Explain. You stand at the edge of a 5m high diving platform. A beach ball is exactly 9 m from the base of the platfo
To the nearest tenth of a meter, what is the distance d from the top of the platform to the beach ball?
the distance, d from the top of the platform to the beach ball is equal to 10.29 m.
We are given that:
Height of the platform = 5 m
distance between bas of the platform and the beach = 9 m
We need to find the distance from the top of the platform to the beach ball.
We know that this distance d will be the hypotenuse of the triangle formed.
So, we have:
Perpendicular = 5 m
Base = 9 m
Hypotenuse = d
So, by using the Pythagoras theorem, we get that:
d² = 5² + 9²
d² = 25 + 81
d² = 106
d = √ 106
d = 10.29 m.
Therefore, we get that, the distance, d from the top of the platform to the beach ball is equal to 10.29 m.

The order of expressions from the least to greatest is [tex]\sqrt{3}[/tex], [tex]\sqrt{pie}[/tex] and 2
In order to find the value of these given expressions, we will have to convert them into a standard form, therefore we will find the value of these expressions by removing the root and finding its actual value
Value of 2 will remain the same as it is already in standard form
Value of [tex]\sqrt{3}[/tex] in standard form = 1.732
Value of [tex]\sqrt{pie}[/tex] in standard form = [tex]\sqrt{3.1459}[/tex] = 1.77

Find the measurement indicated in each parallelogram.

the measurement of angle ∠D in parallelogram ABCD would be 57°.
What is Parallelogram?A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal.
In parallelogram CDEF,
∠C = ∠D
87 = 93 + 2x
2x = 87 - 93
2x = -6
x = -3
So the measurement of ∠D = 93 + 2(-2) = 89
In parallelogram ABCD,
∠A =∠C
57 = 3x + 21
3x = 57 - 21
3x = 36
x = 12
So the measurement of ∠C = 3(12) + 21 = 57

Given that,
A square measuring 8 inches by 6 inches needs squares of side. A cut out of each corner so that the sides can be folded into a box without a top.
How much area a box can occupy is determined by its volume. You need to know a box's length, width, and height in order to compute its volume. By multiplying the base area by the box's height, one can get the volume of a box.
The measurement of how much space an object may occupy is called volume, which is also known as capacity. Both regular and irregular objects may be present. Cubes, blocks, cylinders, pyramids, cones, and spheres are examples of common objects.
A: area of the base
L: Length of the base

Step-by-step explanation:
Given data,
x sin y - 2y^3 - 5 = 7x
Differentiate with each term with respect to the independent variable,
[tex]\frac{d}{dx}[/tex] (x sin y) - [tex]\frac{d}{dx}[/tex] (2y^3) - [tex]\frac{d}{dx}[/tex] (5) = [tex]\frac{d}{dx}[/tex] (7x)
Apply to the product rule,
sin y * [tex]\frac{d}{dx}[/tex] (x) + x * [tex]\frac{d}{dx}[/tex] (sin y) - [tex]\frac{d}{dx}[/tex] (2 [tex]y^{3}[/tex]) - [tex]\frac{d}{dx}[/tex] (5) = [tex]\frac{d}{dx}[/tex] (7x)
Apply the chain rule,
sin y * [tex]\frac{d}{dx}[/tex] (x) + x* [tex]\frac{d}{dy}[/tex] (sin y) * [tex]\frac{dy}{dx}[/tex] - [tex]\frac{d}{dy}[/tex] (2 [tex]y^{3}[/tex])* [tex]\frac{dy}{dx}[/tex] - [tex]\frac{d}{dx}[/tex] (5) = [tex]\frac{d}{dx}[/tex] (7x)
Take out the coefficients,
sin y * [tex]\frac{d}{dx}[/tex] (x) + x * [tex]\frac{d}{dy}[/tex] (sin y) * [tex]\frac{dy}{dx}[/tex] -2 [tex]\frac{d}{dy}[/tex] ([tex]y^{3}[/tex]) * [tex]\frac{dy}{dx}[/tex] - [tex]\frac{d}{dx}[/tex] (5) = 7 * [tex]\frac{d}{dx}[/tex] (x)
Differentiate the constants and power functions,
sin y + x * [tex]\frac{d}{dy}[/tex] (sin y) * [tex]\frac{dy}{dx}[/tex] - 2 * 3 * [tex]y^{2}[/tex] * [tex]\frac{dy}{dx}[/tex] = 7
Differentiate sin (x),
sin y + cos y * [tex]\frac{dy}{dx}[/tex] - 2 * 3 * [tex]y^{2}[/tex] * [tex]\frac{dy}{dx}[/tex] = 7
Isolate,
[tex]\frac{dy}{dx}[/tex] = [ 7-sin y ] / (-6 [tex]y^{2}[/tex] + x cos y )
Therefore,
[tex]\frac{dy}{dx}[/tex] = [tex]\frac{ 7 - sin y }{ -6 y^{2} + x cos y }[/tex]
