Answer:
x = 15
5x + 55 = 2x +100, plug in 15 and they are equal
Answer:
slope = - 
Step-by-step explanation:
Parallel lines have equal slopes thus the slope of a parallel line will be equal to the slope of PQ
To calculate slope m use the slope formula
m = 
with (x₁, y₁ ) = P(- 2, 4) and (x₂, y₂ ) = Q(6, - 2)
m =
=
= - 
The area of a triangle is one half the area for a rectangle because the triangle is half of a rectangle with equal base and height
