Answer:
a)
Step-by-step explanation:
Cost function = revenue function - profit function
= -0.3x² + 150x - [-0.5x² + 250x - 300]
= -0.3x² + 150x + 0.5x² - 250x +300
= -0.3x² + 0.5x² + 150x - 250x + 300 {Combine like terms}
= 0.2x² - 100x + 300
Find the perimeter of the garden find out what kind of triangle the garden is for example if it is a right triangle it has to equal up to 90.
To find the area remember that A=b•h2 as a=area
Answer:
Step-by-step explanation:
This right triangle is on a grid.
The area is the height * base/2
The base is on a line segment parallel to the x axis which is 6 squares.
The height is on a line segment parallel to the y axis which is 2 squares
The area is the height * base /2
Area = 6 * 2 /2 = 12/2 = 6 square units.
Answer:

Step-by-step explanation:
This is the product of a binomial (two terms) in the variable y with a trinomial (three terms) in the variable y as well. Arrange the terms of each expression as noted in the attached image, and complete the boxes with the products of each vertical header with each horizontal header in the appropriate cell of the table. Then combine all like terms (marked in orange and green) to get the final answer:
