What are the zeros of the polynomial function
f(x) = x^3 + x^2 - 20x

choices:
0, -5, -4
0, -5, 4
0, 5, -4
0, 5, 4

answer: h

step-by-step explanation:

60: 45 =12: 9 =4: 3 so the answer is 4: 3

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
