3. The answer is 18 because 12➗4= 3 so 6*3=18
Answer: hypotenuse = 
Step-by-step explanation: Pythagorean theorem states that square of hypotenuse (h) equals the sum of squares of each side (
) of the right triangle, .i.e.:

In this question:
= 
2bc
Substituing and taking square root to find hypotenuse:

Calculating:


=
, then:


Hypotenuse for the right-angled triangle is
units
Rewritten: y=15x + 50
slope: 15
y intercept: (0,50)
The answer would be 3 root 11
