What is x2 + 6x = x2 – 6x as a system?

a.) y = x2 + 6x
y = x2 – 6x

b.) y = –x2 + 6x
y = x2 – 6x

c.) y = –x2 – 6x
y = x2 – 6x
and can you work it out because i am so confused?

its 50 miles away from the starting point

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
