Answer:
3 6 9 12
Step-by-step explanation:
those are the multiple of 3
Remember that a function composed with its inverse results in the placeholder
aka
(f o f⁻¹)(x)=x
so
(f o f⁻¹)(4)=4
12.4 / 6.2 = 2
so other side of enlarged rectangle = 1.8 x 2 = 3.6
Perimeter of enlarged rectangle = 2(3.6 + 12.4) = 32
Answer: 32 feet
------------------------
Another way to do:
12.4 / 6.2 = 2
SF = 2
The original rectangle has a perimeter of 16
Perimeter of the enlarged rectangle = 16 x 2 = 32
Answer: 32 feet
A = 180
b = 180
c = 180
180+180-180 = 180
