Answer:
The height of wall is 3 feet and length of wall is 5 feet
Step-by-step explanation:
Given as :
The Area of retaining wall = 15 square feet
Let The width of wall = W feet
The Height of wall = ( W - 2 ) feet
Now, Area of Rectangle = Height width
Or , 15 ft² = ( W - 2 ) ft × W ft
Or, 15 = W² - 2 W
Or, W² - 2 W - 15 = 0
Or, W² - 5 W + 3 W - 15 = 0
Or, W ( W - 5 ) + 3 ( W - 5 ) = 0
So , ( W - 5 ) ( W + 3 ) = 0
So, W = 5 , - 3
∴ The width of wall = W = 5 feet
And The Height of wall = ( W - 2 ) = 5 - 2 = 3 feet
Hence The height of wall is 3 feet and length of wall is 5 feet. Answer
14 + 12 = 26
26 + 10 = 36
36 + 8 = 44
44 + 6 = 50
(notice the pattern)
14, 26, 36, 44, 50
Answer:
5n + 4
Step-by-step explanation:
7n + 4 + (-2n)
= 7n + 4 - 2n
= 5n + 4

you have to take the amount she reads and divide it by the number of pages per 303030 minutes then take the answer times the amount of time it takes
200200200/252525=792.7935848
792.7935848x303030=240240240
