The net below shows the dimensions of Michelle’s living room. She is going to put wallpaper on the living room walls.
What is the difference, in square yards, between the total and lateral surface areas of the room?
Answer this, please

Answer:

The difference between the total and lateral surface areas of the room is 42 square yards.

Step-by-step explanation:

The lateral surface area of an object is the surface area of everything EXCEPT for the top and bottom of the object.

2(6*4.2) + 2(4.2*3.5) = 79.8 square yards

The total surface area of an object is everything INCLUDING the top and bottom of the object.

79.8 + 2(6*3.5) = 121.8 square yards

121.8 - 79.8 = 42 square yards

okok so.
context.
"Raul’s grandfather is Miguel, and Raul’s sister is Paula. Raul’s age is the same as his grandfather’s age minus 60 times the age of his sister. Miguel is 65 years old. Using the results from Part C, write an equation to find Paula’s age, p (in years)." answer: "r = 65 - 60p"

"Rewrite the equation from Part D by factoring the side that contains the variable p." answer: "r = 5 (13 - 12p)"

"Solve the equation for p to find Paula’s age. Express her age (in years) as a fraction." "answer: p = -1/60r + 12/12"

thingy i need help with is "How many months old is Paula?"

Which equation is an example of slope-intercept form of a line?

In particular this amazing conjecture asserts that if ζ(1) is equal to 0, then there are an infinite number of rational points (solutions), and conversely, if ζ(1) is not equal to 0, then there is only a finite number of such points.
