Answer:
Step-by-step explanation:
f(4) = -1
g(4) = -2
(f + g)(4) = f(4) + g(4) = -3
Hope that helps!

Step-by-step explanation:
You are looking for the perimeter, so you need to add 11+11+7+7. That equals 36.
Answer:
see explanation
Step-by-step explanation:
Calculate the slopes between pairs of the 3 points using the slope formula
m =
with (x₁, y₁ ) = (- 9, 3) and (x₂, y₂ ) = (- 3, 9)
m = = = = 1
Repeat with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (- 3, 9)
m = = = - 1
If lines are perpendicular then the product of their slopes = - 1 , then
1 × - 1 = -1
Thus there is a right angle between the 2 lines
Then triangle is right- angled
