1. Rotate 180° about (0,0).
Α. (2,6)
D (2,2)
C (3,0)
В. (4,0)

i dont know what you want me to answer for this but im guessing 2: 11?

umm you say your want to . but you do know that this is the mathematics.  

o~o

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
