For this case we have that by definition, the distance between two points is given by:

We have the following points:

Substituting we have:

Thus, the distance between the points is

4 ( -3 )
= -12
Answer:
x=25 =18
Step-by-step explanation:
Right angle =90°
you are given 40, therefore 2x has to equal up to 50.
2x=50 divide both sides by 2
x=25
straight line=180°
you are given 90, therefore 5y has to equal to 90.
5y=90
divide both sides by 5
y=18
Answer: 5/9
Solution: 2x^2+16x-10=0
According to formula: X=(-16+_sqrt(16^2-(-10•2)) / 2•2
X=5/9
