Answer: I believe it is the vertex form.....
Answer:
Step-by-step explanation:
Since surface area consists of the sum of the outer faces of each polygon, the ratio of the two surface areas will be equal to the ratio of the side lengths squared (since we multiply them to get area).
The ratio of the corresponding side lengths of the solids are . Therefore, the ratio of their surface areas must be
Answer:
Step-by-step explanation:
y + 6 = 12(x - 7)
y + 6 = 12x - 84
y = 12x - 90
Part A
P = perimeter of square
P = add up the four sides
P = N+N+N+N
P = 4*N
where N is the side length of the square
The perimeter of the square is at most 22 ft, which means 22 ft is the largest the perimeter can be. Think of it as the ceiling.
So P = 22 or P < 22. We can combine those two ideas to get
(P is less than or equal to 22)
Replace P with 4N and solve for N
divide both sides by 4
The side length N can be 5.5 ft or smaller
-----------------------------------------------------------------------------------------------
Part B
The result we got from part A above was
which means N can be equal to 5.5 or it can be smaller than 5.5
So this describes N = 2.5, N = 4.8, and N = 5.2
The values N = 5.8 and N = 6 are too big
So the answers to part B are 2.5 ft, 4.8 ft, and 5.2 ft
