Ok so it's a proportion so this fraction is to this fraction. the smaller rectangle has sides 4 and 12. the larger one has 8 and x. so u set it up 4/12=8/x. the 4 and 8 r both the short sides so u want those on top and 12 and x r long sides so those on bottom. since that is not an answer option u can set it up as 8/4=x/12 because u still keep the variables of the same rectangle from being multipled with each other. so answer #2 is correct
Answer:
2/5
Step-by-step explanation:
Answer:
2.40 x 10^22
Step-by-step explanation:
F(x) = 2w + I = 2w 5000/w
f'(x) = 2 - 5000 / w^2
Fencing is minimum, so f(x) = 0
2 - 5000/w^2 = 0
2 = 5000 /w^2
2w^2 = 5000
w = 50
I = 5000/2
= 1000
2w + I
= 200
hope this helps
Assuming the length increases by 2 meters, the sides are:
3, 5, 7, 9, 11, and the 6th side is 13
