Answer:
Step-by-step explanation:
The area of a rectangle is given by the product of its length and width. Therefore, the area of the rectangle is:
A(x) = L(x) ⋅ W(x) = 2x(8x^2 - 4x + 1)
Simplifying the expression, we get:
A(x) = 16x^3 - 8x^2 + 2x
Therefore, the answer is (D) (L ⋅ W)(x) = 16x3 − 8x2 + 2x.

Do leading zeros count as significant figures?
Absolutely, because they show how big a number is, average leading zeros are regarded as significant digits. Leading zeros are counted as important figures since they help determine the decimal point's location and the size of the number.
Leading zeros in a number are important figures. This implies that when counting the total number of significant figures in a number, they are taken into account. The reason for this is that preceding zeros reveal the location of the decimal point and, hence, the size of the number. Because the leading zero signifies that the number is in hundredths, the number 0.002, for instance, has three significant figures. The number would be read as two rather than two hundredths without the leading zero. Due to their significance in assessing a number's precision, leading zeros should always be counted among the significant figures.

K'(-2, 1) is the coordinate of the image of point K, found by multiplying the original x-coordinate of the point K (2) by -1. To reflect the triangle over the y-axis, the x-coordinate of each point is multiplied by -1.
What is triangle?Triangle is a three-sided geometric shape which has three angles and three sides. The three sides of a triangle are typically referred to as the base, the height, and the hypotenuse. A triangle can be classified as either right, obtuse, or acute depending on the measure of its angles. Right triangles have one right angle, obtuse triangles have one obtuse angle, and acute triangles have three acute angles.
The coordinate of the image of point K is K’(-2, 1). This means that the x-coordinate of the point is -2 and the y-coordinate of the point is 1. This can be found by multiplying the original x-coordinate of the point K (2) by -1. The y-coordinate of point K remains the same, so the y-coordinate of the image of point K is 1.

Graph the equation x + 4y - 3 = 0
The graph of the function is attached below.
What is the Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
Given a function x +4y -3 = 0
To graph the equation x + 4y - 3 = 0, we need to find at least two points that satisfy the equation and plot them on a coordinate plane. To do this, we can use the intercept method.
First, we can find the x-intercept by setting y = 0 in the equation and solving for x:
x + 4(0) - 3 = 0
x = 3
So the x-intercept is (3, 0).
Next, we can find the y-intercept by setting x = 0 in the equation and solving for y:
0 + 4y - 3 = 0
4y = 3
y = 3/4
So the y-intercept is (0, 3/4).

pls helppppp its math and its pretty hard
A maintenance worker needs to wax a restaurant floor shaped like the image shown. A six-sided figure. There is a horizontal base of 35 feet then another horizontal base below it of 20 feet. The longest side is to the right and is 40 feet. The top is 30 feet. There is a perpendicular from the vertex of the top to the first base of 35 that is labeled 15 feet. If the wax cost $1.38 a square foot, how much will the wax cost to cover the floor? $1,224.75 $1,569.75 $2,104.50 $2,449.50
If the wax cost $1.38 a square foot, the cost of wax to cover the area of the floor is $1,569.75.
The correct option is B.
What is the total area of the floor?The total area of the floor is calculated from the shape of the floor.
The floor is made up of a trapezoid and a rectangle.
The area of a trapezoid can be calculated as:
A = (a + b)/2 * h
where
a and b are the lengths of the bases and h is the height.
The trapezoid has a height of 15 feet and bases of 35 feet and (20 - 20) or 10 feet. So its area is:
A = (35 + 10)/2 * 15
A = 337.5 square feet
The rectangle has a base of 20 feet and a height of 40 feet. So its area is:
A =20 * 40
A = 800 square feet
The total area of the figure is the sum of the areas of the trapezoid and triangle:
A = 337.5 + 800
A = 1137.5 square feet
Finally, to find the cost of the wax, we multiply the area by the cost per square foot:
Cost = 1137.5 * $1.38
Cost = $1569.75

a line y = 3x - 5 is reflected in x = a so that the image is given by y = 1 - 3x. what is the value of A?
Answer: The line y = 3x - 5 can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept. In this case, m = 3 and b = -5.
When a line is reflected across the x-axis, the slope of the line changes sign, but the y-intercept remains the same. This means that if the original line has slope m and y-intercept b, the reflected line will have slope -m and y-intercept b.
For the image, y = 1 - 3x, the slope is -3 and the y-intercept is 1.
To find the value of a, we can set the two lines equal to each other and solve for x:
3x - 5 = 1 - 3x
Solving for x, we get:
4x = 6
x = 3/2
So the line of reflection, x = a, passes through
