Answer:
see explanation
Step-by-step explanation:
Given
A =
h(x + y)
Multiply both sides by 2 to eliminate the fraction
2A = h(x + y) ( divide both sides by h )
= x + y ( subtract x from both sides )
y =
- x
Answer:
option (4)
Step-by-step explanation:
Calculate the length using the distance formula
d = 
with (x₁, y₁ ) = A(2, 2) and (x₂, y₂ ) = B(- 6, 4)
AB = 
= 
= 
= 
≈ 8.25 ( to 2 dec. places )
