Step-by-step explanation:
----------------------------------------
Define x:
----------------------------------------
Let x be the length of the pool.
Length of the pool and its border = x + 1 + 1
Length of the pool and its border = x + 2
----------------------------------------
Given area = 361 ft², find x:
----------------------------------------
(x+2)² = 361
x+ 2 = √361
x + 2 = 19
x = 19 - 2
x = 17
----------------------------------------
Find Length of the pool:
----------------------------------------
Length of the pool = x = 17 feet
----------------------------------------
Find Area of the pool:
----------------------------------------
Area = 17 x 17
Area = 289 ft²
------------------------------------------------------------
Answer: Area of the pool = 289 ft²
------------------------------------------------------------
Answer:
y= -x+b
Step-by-step explanation:
hello :
the slope for the line : - x+y=2 is 1 because -x+y = 2 means y= 1x+2
all lines perpendicular to the line -x+y=2 have equation : y = ax+b
when : a×(1) = -1 so : a=-1
an equation is : y= -x+b
look the graph for the line : -x+y=2 (color red) and some lines
perpendicular to this line
