<span>f(x) = -3x^2</span>
insert x=2
y=-3*2^2
y=-3*4
y=-12
so your pair is (2,-12)
It is 5 because of the Pythagorean Theorem. 4^2 + 3^2 = c^2
16 + 9 = 25
v25 = 5
The answer is C.
90/105=6/7
Hope this helps!
I got 25/21 or 1 4/21, but there’s a possibility I could’ve made a mistake in my math so you should double check it just in case.
