I'm not sure what you're asking but if you're looking for simplification, here it is. -7x² + 2x - 12
Answer:
The principal square root of -4 is 2i.
Step-by-step explanation:
= 2i
We have the following steps to get the answer:
Applying radical rule 
We get 
As per imaginary rule we know that 
= 
Now 
Hence, the answer is 2i.
Answer:
I would say that they are different because if x - a has a value to the equation then that means a - x will not have the same value because it may be rearranged to a different equation but that doesn't mean that they will have the same value. that explain why x - a and a - x are not the same
3.906m
Step-by-step explanation:
from the topic angle of elevation and depression
putting down the above question diagrammatically
we have a triangle
The angle of elevation pad looking up = 38°
using the tangent rule TOA
TAN∅= OPPOSITE/ADJACENT
we have
tan 38° = x/5
x= tan 38° × 5
x= 0.781 * 5
x = 3.906m
