The length of a rectangle is 16 units more than its width. The area of the rectangle can be expressed as
x^4 – 64.
Which expression represents the width of the rectangle?

Answers

Hiiii your answer is (x2+8)(x2-8)

The width of the rectangle represented by the expression (x⁴ – 64)/x.

What is rectangular shape?

A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle.

Given:

The length of a rectangle is 16 units more than its width.

Let the length is x units.

Then width = (x + 16) units.

The area of the rectangle can be expressed as

x⁴ – 64 = length x width

x⁴ – 64 = x (x + 16)

x + 16 =(x⁴ – 64)/x

Therefore, the width expression is (x⁴ – 64)/x.

Answers

Answer:

Step-by-step explanation:

Answer:

Answer

5.0/5

11

Answer: Choice D.  < B = < A

ie, "angle B = angle A"

The symmetric property is if y = x then x = y. The order of what is on the left or right side of the equation does not matter. It's like saying 2+3 = 5 is the same as 5 = 2+3.

This idea can be extended to congruences because congruent angles have the same measure.

So < A = < B is the same as < B = < A.

A cylinder has a diameter of 6 cm and a height of 14 cm. What is the approximate volume of a cone with the same diameter and height
as the cylinder?

Answers

The approximate volume of a cone with the same diameter and height as the cylinder is 131.95 cm³.

How to calculate the volume of a cylinder?

In Mathematics and Geometry, the volume of a cylinder can be calculated by using this formula:

Volume of a cylinder, V = πr²h

Where:

V represents the volume of a cylinder.h represents the height of a cylinder.r represents the radius of a cylinder.

Radius = diameter/2 = 6/2 = 3 cm.

By substituting the given parameters into the volume of a cylinder formula, we have the following;

Volume of cylinder, V = π × 3² × 14

Volume of cylinder, V = π × 9 × 14

Volume of cylinder, V = 395.8 cm³.

For the volume of this cone, we have:

Volume of cone, V = 1/3 × πr²h

Volume of cone, V = 1/3 × 395.8

Volume of cone, V = 131.95 cm³.

O O O O

Answers

Answer:

The correct options that describe the inequality (y + 1)² > 6·(x - 2)

1) Because only the 'y' quantity is squared the curve is a parabola

2) The parabola opens right because 6 is in front of the 'x' quantity

3) The shading area is outside the parabola because (0, 0) satisfies the inequality

4) The values subtracted from 'x', and 'y' in the equation are the coordinates of the vertex

Step-by-step explanation:

The given inequality graphed by Miranda is presented as follows;

(y + 1)² > 6·(x - 2)

By simplification, we get;

Given that the inequality is of the form (y - k)² > 4·p·(x - h), we have;

The curve is a parabola as only the 'y' quantity is squared

-k = 1

∴ k = -1

4·p = 6

∴ p = 6/4 = 3/2 = 1.5

p = 1.5

-h = -2

∴ h = 2

The vertex of the parabola = (h, k) = (2, -1)

The axis of symmetry = The x-axis

p = 1.5 > 0, therefore, the parabola opens right

Therefore, the parabola opens right because 6 is in front of the 'x' quantity

There is a strict inequality therefore the boundary is not included in the solution set

When x = 0 and y = 0, we have;

(y + 1)² > 6·(x - 2)

(0 + 1)² > 6·(0 - 2)

1² > 6 × (-2)

1 > -12, which satisfies the inequality and (0, 0) is on the left and below the vertex, therefore, the shaded area is outside the parabola

The vertex of the parabola given in the form, (y - k)² > 4·p·(x - h), is (h, k), which are the values subtracted from 'x', and 'y' in the equation

Therefore, the vertex of the given parabola, (y + 1)² > 6·(x - 2) = (2, -1)

8n - 2(n+5) = -3 + 6n

Answers

Answer:

No solution

Step-by-step explanation:

There are no values of  n  that make the equation true.

8n −2(n+5) = −3 + 6n

First Step: Simplify both sides of the equation

(Distribute) 8n + (-2)(n) + (-2)(5) = -3 + 62

8n + -2n + -10 = -3 + 6n

(Combine like terms) (8n + −2n) + (−10) = 6n − 3

6n + −10 = 6n − 3

6n  − 10 =  6n − 3

Step 2: Subtract 6n from both sides

6n − 10 − 6n = 6n − 3 − 6n

-10 = -3

Step 3: Add 10 to both sides

-10 + 10 = -3 + 10

0 = 7 (No Solution) (Answer)
