If you are asking if it is true, it is. But I am really not sure what you are asking.
To find the circumference of a circle, use this formula: 2πr
Answer:y = 2/3
Step-by-step explanation:
2x + y = 10
x - y = 4
-----------------add
3x = 14
x = 14/3
x - y = 4
14/3 - y = 4
-y = 4 - 14/3
-y = 12/3 - 14/3
-y = -2/3
y = 2/3 <==
Answer:
-14 or 13
Step-by-step explanation:
x + x^2 = 182
x^2 + x - 182 = 0
rearrange and solve by completing the square
x^2 + x = 182
x^2 + x + 1/4 = 182.25
(x + 1/2)(x + 1/2) = 182.25
(x + 1/2)^2 = 182.25
x + 1/2 = root 182.25
x = + or - root 182.25 - 0.5
x = + or - 13.5 - 0.5
x = 13 or x = - 14
