For the first digit, we have 5 options that are 4,5,6,7,8 . For the second digit, we have 4 options which are 3,4,5 or 6 and for the third digit, we have the options of all numbers except 2 or 5 that is 1,3,4,6,7,8,9,0 . SO we have 8 options for third digit . So to find the total number of options, we need to multiply all the possible options for each digit that is 5 times 4 times 8 = 160 . So the number of possible options are 160 .

Answer: 4 square inches</h3>
Explanation:
Square the linear scale factor to get 5^2 = 25
This means that,
new area = 25*(old area)
We take this idea in reverse to find the old area
old area = (new area)/25
old area = (100 sq inches)/25
old area = 4 square inches
The answer is 29. If you put it in an equation, it looks like 90=(x*3)+3. If you -3 from each side, you get 87=x*3. Divide each side by 3, and you get x=29.
