You would rotate it by 360 degrees so you can see the back of it
Judging by the question you should indeed use the equation 0.2 x n = 15.
To solve this you must divide both sides by 0.2, which would result in n=75.
So, if the question is 'True or False: Use the equation 0.2xn=15 to find the value of n' then the answer is True.
Y = x^2 . . . (1)
y = -x + 2 . . . (2)
Putting (1) into (2) gives,
x^2 = -x + 2
x^2 + x - 2 = 0
x^2 - x + 2x - 2 = 0
x(x - 1) + 2(x - 1) = 0
(x + 2)(x - 1) = 0
x = -2 or x = 1
y = (-2)^2 or y = (1)^2
y = 4 or y = 1
Solution is (-2, 4) and (1, 1)
