2.
Rectangle 1 has 1 length x and width y. Rectangle 2 is
made by multiplying each dimension
of Rectangle 1 by a
factor of k, where k > 0.
2 similar? Why or why not?
(a) Are Rectangle 1 and Rectangle
perimeter of Rectangle 2 is k times the perimeter of Rectangle 1.
Write a paragraph proof to show that the perimeter
(c)
show that the area of Rectangle 2 is K2 times the area of Rectangle 1.
Write a paragraph proof to

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.

4y - 6 + y^2 - 9 = y^2 + 4y - 15
