504 because when you multiply 9 by 8 and then by 7 (9x8x7) you get 504.
2. because each x number times 2 plus one is equal to the y range
2y - x = 5
x^2 + y^2 - 25 = 0
x = 2y - 5
(2y-5)^2 + y^2 - 25 = 0
(2y-5)(2y-5) + y^2 - 25 = 0
4y^2 - 20y + 25 + y^2 - 25 = 0
5y^2 - 20y = 0
y = 0 , y = 4
x = 2y - 5 , when y = 0
x = - 5
x = 2y - 5 , when y = 4
x = 8 - 5
x = 3
Answer:
160 ft
Step-by-step explanation:
the length of one side would be √1600 which is 40 so 40• 4 is 160
Answer:
The answer is $61.20
