The area of the shape as a sum is 2x^2 + 5x + 2.

The area of the shape as a product is (x+2) (2x+1).

What is area of a shape?

A figure surrounded by a barrier is referred to as a shape. Numerous things in shapes like square, rectangle, round, etc. are all around us.

The space around by a shape's perimeter or boundary is known as its area. Using particular mathematical methods, we may determine the area of shape for various geometric shapes.

Area as a sum

For this, we will simply add all the values given in the figure

⇒ x^2 + x^2 + x + x + x + x + x + 1 + 1

⇒ 2x^2 + 5x + 2

So, the area of the shape as a sum is 2x^2 + 5x + 2.

Area as a product

The shape given is a rectangle

Area of a rectangle is length * width

Now, the length is x+2 and the width is 2x+1

So, the area is

⇒(x+2) (2x+1)

So, the area of the shape as a product is (x+2) (2x+1).

Hence, the area of the shape as a sum and as a product are obtained.

To solve for x in an equation, you will need to use algebraic techniques to isolate x on one side of the equation. The specific steps will depend on the equation you are trying to solve.

Here are a few examples of how to solve for x in different types of equations:

Linear equation: An equation of the form ax + b = 0, where a and b are constants. To solve for x, you would subtract b from both sides and then divide both sides by a.

Quadratic equation: An equation of the form ax^2 + bx + c = 0, where a, b, and c are constants. To solve for x, you would factor the equation or use the quadratic formula.

System of equations: A set of equations with multiple variables, such as 2x + 3y = 5 and 4x + 6y = 10. To solve for x, you would use elimination or substitution method.

Two parallel lines called the x axis and the y axis are employed for graph or plot points. The x axis is on the horizontal number line, while the y axis is on the vertical line. The positive and negative axes of the x axis are arranged to the right and left of the origin, respectively.

The following format is employed to plot a point's coordinates: (x, y). As is evident, the x-coordinate is frequently placed first. For example, we have determined the x and y coordinates for the respective points B and D in the diagram we have been using. Point B's x-coordinate is 100.

Any position on the plane may have its x- and y-coordinates established using its horizontal and vertical distances from the origin. In essence, what we do when we sketch a point is the complete antithesis of what we do here.

Labelling:

Our x-coordinate is as follows:

Positive if it's in the appropriate area of our plane.

If it is on the left side of our plot, it is not ideal.

If it is on the x-axis, then it is 0.

Our y-coordinate is as follows:

If it is in the top part of our plot, it is a good indicator.

If it is in the bottom part of our plot, it is not good.

If it is on the y-axis, it will be 0.

Answer:

B.The car had been driven 65,000 miles when Franklin purchased it.

When we have a right triangle, Cos = a / h, according to the cosine law. In this situation, the letter "a" stands for adjacent.

The hypotenuse, denoted by the letter "h," can be calculated using the Pythagorean Theorem. All you need to get cosine is the hypotenuse and the neighboring side.

The ratio of the length of the side next to the angle divided by the length of the triangle's hypotenuse is known as the cosine of an angle.

The triangle's sides, a, b, and c, are determined using the cosine formula, which is given as

c = [a2 + b2 - 2ab cos C]

According to the Cosine Rule in trigonometry, the square of the length of any side of a given triangle equals the sum of the squares of the other sides minus twice the product of the other two sides multiplied by the cosine of the angle that separates them.

The factors of equation, x²- 9x + 18 = 0 are (x- 3)(x- 6), where x is variable.

Factorization is a mathematical process that is applied to split a number, an expression, matrix etc. into the product of factors such that when we multiplied these factors again we get the original one. We have, an equation is x² - 9x + 18 = 0 --(*) and we have to factorize it. Steps to factorize the quadratic equation, ax² + bx + c = 0, are :

Now, comparing the equation (*) with standard equation we get, a = 1 , b = -9 , c = 18.

So, Split the number 9, into 6 and 3

=> x² - 9x + 18

=> x² - 6x - 3x + 18

=> (x² - 6x) - (3x - 18) [ grouping]

=> x( x - 6) - 3( x-6) [ factors of group ]

=> (x- 3)(x- 6)

so, x² - 9x + 18 = (x- 3)(x- 6) = 0 helps to get the solution of it (x- 3)(x- 6) = 0 => x = 6,3

Hence, the required factors are (x- 3)(x- 6).

The radian measure of an angle theta is the length of the arc that subtended angle 2Pi

We can measure angles in two forms degrees or Radians.

Radian can be described as a measure of the angle subtended by a circular arc. It can be defined as the ratio of the arc length subtending angle to the radius of the circle.

One radian is the measure of the angle subtended by an arc that is equal to the radius of the circle.

Therefore, the radians measure an angle theta the length of the arc.

Θ =s/r ,

where theta is the angle subtended, s is the arc length and r is the radius of the circle.

We know that the 2π radians = 360 degrees.

That subtends the angle in a circle of radius 2Pi

The difference in volume between the cereal box and pastry box is 167.991 cubic inches.

What are Dimensions?

Dimensions refer to the measurement of the size or extent of an object or space in a particular direction, such as length, width, and height. In the context of boxes, dimensions are used to describe the length, width, and height of a box, usually given in inches or centimeters.

To find the volume of a rectangular box, we use the formula:

Volume = length x width x height

Let's first find the volume of the cereal box:

Volume of cereal box = 7 inches x 12 inches x 2 inches = 168 cubic inches

Now let's find the volume of the pastry box:

Volume of pastry box = 3% inches x 3% inches x 2% inches = 0.009 cubic inches

Now, to find the difference in volume between the two boxes, we subtract the volume of the pastry box from the volume of the cereal box:

168 cubic inches - 0.009 cubic inches = 167.991 cubic inches

Hence, the difference in volume between the cereal box and pastry box is 167.991 cubic inches.
