Well first you have to know what i is. i is the sqrt of -1 so try doing 3+5(sqrt-1)/1+sqrt-1. I don't know how to solve it though sorry
Is z an angle? if so, i'll use the ration
[email protected]=perpendicular/base
tanZ=15/20=3/4 answer
Yes I love this problem so good
Slope = -2/1
work is provided in the image attached.
steps
(x) = 5x^2-3x+7
refine
x=5x^2-3x+7
Switch sides
5x^2-3x+7-x=x-x
Subtract x from both sides
5x^2-4x+7=0
Solve with the quadratic formula
