Answer:
d = 13
Step-by-step explanation:
The distance formula in a complex plane is 
. Let us say that points (a,b) are (-2,-3) and points (s,t) are (3,9), both coordinates derived from given. Substitute the numbers into the equation to get the distance.
d = 
d = 13
The answer would be 2√5/5
As a rule, you cannot have any radical as a denominator. That's why you gotta multiply √5 with √5 which would be √25. The square root of this is 5, and now you have disposed of the radical! Hurray. However, keep in mind, that when you multiply √5, you also multiply it to the numerator. So, yeah, after this, you get the answer.
Hopefully, my explanation makes sense. :)
Answer:
5√2
Step-by-step explanation:
The 45-45-90 triangle theorem states that the length of a triangle's hypotenuse is √2 times the length of the triangle's leg. In this problem, the triangle's leg is equal to 5, meaning that the hypotenuse would be 5 x √2, which is equal to 5√2.
If the variables disappear and you get a statement that is never true,such as 0=5 or 4=7 then there is no solution meaning when graphed the two equations will form parallel lines which never interact
A.true
Because congruent angles are exactly the same measure
