Answer:
The length is 48
The width is 20
Step-by-step explanation:
When 2 rectangles (figures) are similar, the ratio of corresponding sides are equal.
This rectangle is 5 by 12, so the shorter side (corresponding to 5) to the longer side (corresponding to 12) would be the same ratio, 5:12.
Let shorter side be s, and
longer side be l
It says, long side is 8 greater than twice short, we can write this as:

In similar rectangles, we have said the corresponding sides' ratio are equal, so we could write:

Now, we replace the new found expression for "l" onto this and cross multiply and solve for s first:

So the shorter side is 20. and hence the longer side would be:
l = 2s + 8
l = 2(20) + 8
l = 40 + 8
l = 48
The longer side is 48.
The length is 48
The width is 20
Answer: C - the fourth month
Step-by-step explanation: If it doubles every month, then at 6 months there should be 32 times the original affected area. 1/8 of 32 is 4.
The answer would be d=8t
This would be because the time they want is 1 hour. So when you plug in t as 1 you need d to equal 8. So you just have to change that 6 in the first equation to an 8. This new equation means that the person can travel 8 miles every hour.
Expanded form is when you take a number, and add its digits together, reforming the number. For example, 1,523 would be 1,000 + 500 + 20 + 3
Here are a few examples:
2,000 + 400 + 50 + 7 = 2,457
200,000 + 700 + 10 + 2 = 200,712
50,000 + 800 + 50 + 6 = 50,856
60,000,000 + 200,000 + 50,000 + 1,000 + 400 + 20 + 3 = 60,251,423
So, 20,484,163 is equal to
20,000,000 + 400,000 + 80,000 + 4,000 + 100 + 60 + 3 = 20,484,163
I hope I helped!
