Answer:
the third side is 4.
Step-by-step explanation:
Using Pythagorean theorem of a^2 + b^2 = c^2 for right triangles, substitute
the numbers to show (
+ 
= 
and solve for b. The square root and square cancel each other out, so you get 65 + = 81.
Subtract 65 from both sides to get = 16.
Then take the square root of both sides to get b = 
which equals 4.

Answer:
the top one
Step-by-step explanation:
just look at the y intercept, and if it has (0,2) its right
and look also look at if it is going up from left to right or going down, beucase this has a negative slope it should be going down
Answer:
(2, 2 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ 
(x₁ + x₂ ) , (y₁ + y₂ ) ]
Here (x₁, y₁ ) = (A(5, 8) and (x₂, y₂ ) = B(- 1, - 4) , thus
midpoint = [ (5 - 1), (8 - 4 ) ] = (2, 2 )
3(3x - 2)
Distribute (multiply) 2 inside the parentheses.
3 * 3x and 3 * -2
9x - 6
