Answers

Answer 1

Answer:

A) 5x² - 6x + 1

Step-by-step explanation:

In this question, you would have to simplify the expression.

Solve:

(3x² - 2) + (2x² - 6x + 3)

Combine like terms.

3x² - 2 + 2x² - 6x + 3)

5x² - 2 - 6x + 3

5x² - 6x + 1

Since there's no more like terms, we have completely simplified the expression.

Therefore, your answer would be A) 5x² - 6x + 1

The length of a rectangle is

8 inches longer than the

width. If the ratio of the

length to perimeter is 5:16,

what is the area of the

rectangle?

Answers

Answer:

Step-by-step explanation:

The area of the rectangle is 240 square inches if the length of a rectangle is  8 inches longer than the width. If the ratio of the length to the perimeter is 5:16.

What is the area of the rectangle?

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

It is given that:

The length of a rectangle is  8 inches longer than the width. If the ratio of the length to the perimeter is 5:16

As we know, the two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.

Let l and w be the length and width of the rectangle:

l = 8 + w

w = l - 8

l/P = 5/16  (the length to the perimeter is 5:16)

P is the perimeter of the rectangle.

P = 2(l + w)

l/[2(l + w)] = 5/16

16l = 10(l + w)

8l = 5(l + l - 8)

8l = 10l - 40

2l = 40

l =20 inches

w = 20 - 8 = 12 inches

Area = 20x12 = 240 square inches

Thus, the area of the rectangle is 240 square inches if the length of a rectangle is  8 inches longer than the width. If the ratio of the length to the perimeter is 5:16.

To calculate the price, you multiply the area of the floor (width times length) by the price per square foot of carpet. For example, the area of floor that is 12 feet long and 10 feet wide is 120 square feet. To cover that floor with carpet that costs $8 per square foot would cost $960. (12 10 8 = 960.) First, you should create a class named RoomDimension that has two FeetInches objects as attributes: one for the length of the room and one for the width. (You should use the version of the FeetInches class that you created in Programming Challenge 11 with the addition of a multiply member function. You can use this function to calculate the area of the room.) The RoomDimension class should have a member function that returns the area of the room as a FeetInches object. Next, you should create a RoomCarpet class that has a RoomDimension object as an attribute. It should also have an attribute for the cost of the carpet per square foot. The RoomCarpet class should have a member function that returns the total cost of the carpet. Once you have written these classes, use them in an application that asks the user to enter the dimensions of a room and the price per square foot of the desired carpeting. The application should display the total cost of the carpet. please answer will give brainliest What is the molar mass of Ammonium Carbonate? look at this i think this boy likes me Significado de compro sombreros ropa usada que no use ollas sucias juguetes y peluches que cambie por otros how do volcanoes affect earths climate 2.
