The side lengths of rectangle is 3 cm and 1.75 cm and 5.25 cm and 9 cm.
According to the statement
we have given that Rectangle A has side lengths of 6 cm and 3.5 cm
And The side lengths of rectangle B are proportional to the side lengths of rectangle A.
And we have to Find that the What could be the side lengths of rectangle B?
A 3 cm and 1.75 cm
B 5 cm and 2.5 cm
C 7 cm and 7 cm
D 12 cm and 5 cm
E 5.25 cm and 9 cm
Here we see that the side B are proportional to side length A of rectangle.
So,
Let say sides of rectangle B are a and b corresponding to sides 6 and 3.5 cm
=> a/6 = b/3.5
=> a/b = 6/3.5
=> a/b = 12/7
A 3 cm and 1.75 cm
3/1.75 = 12/7
Hence this is proportional
B 5 cm and 2.5 cm
5/2.5 = 2 ≠ 12/7
Not Proportional
C 7 cm and 7 cm
7/7 = 1 ≠ 12/7
Not Proportional
D 12 cm and 5 cm
12/5 ≠ 12/7
Not Proportional
E 5.25 cm and 9 cm
9/5.25 = 36/21 = 12/7
Hence this is proportional
So, 3 cm and 1.75 cm and 5.25 cm and 9 cm could be the side lengths of rectangle B.

Answer:
8 hr to read 288 pages
Step-by-step explanation:
First find pages per hour so divide 72 pages by 2 hours to find per hour.
72/2 = 36 pageper hr
288 divided by 36 pages per hour is 8
5^-2 = .04
5^5 = 3125
.04 x 3125 x 5 = 625
Answer:
y=5x+2
Step-by-step explanation:
First, let's put this into y=mx+b form.
m is the growth, or how much y increases when x increases by 1
b is the initial condition, or the value of y when x equals 0.
So, y=(5)x+2 because y increases by 5 when x increases by 1. and 2 because that is the value of y when x is 0.
Hope that helped.
