Hey there!
In this picture, we have many pairs of adjacent angles:
1 and 2
2 and 4
4 and 3
3 and 1
This is because these pairs are being connected by a vertex and a side.
Hope it helps and have a great day!!!
Are equation for a rectangle is area = (width x length)
(18x - 12) = 6 x length
length = (18x - 12) / 6
length = 3x - 2
The point where the two axes intersect (0,0) it's the point of origin.
Answer: (x2 – 1) – 5(x – 1)
