Answer:
1600 integers
Step-by-step explanation:
Since we have a four digit number, there are four digit placements.
For the first digit, since there can either be a 5 or an 8, we have the arrangement as ²P₁ = 2 ways.
For the second digit, we have ten numbers to choose from, so we have ¹⁰P₁ = 10.
For the third digit, since it neither be a 5 or an 8, we have two less digit from the total of ten digits which is 10 - 2 = 8. So, the number of ways of arranging that is ⁸P₁ = 8.
For the last digit, we have ten numbers to choose from, so we have ¹⁰P₁ = 10.
So, the number of integers that can be formed are 2 × 10 × 8 × 10 = 20 × 80 = 1600 integers

Answer:
To be Honest I kinda do know but I can solve the equation for you if that helps
Step-by-step explanation:
5x+15y-6 is the answer
first you will add all of them and then distribute
Remove parentheses
=3x-18+15y+6+2x+6
Group like terms
=3x+2x+15y-18+6+6
Add similar elements
=5x+15y-18+6+6
Finally Add/Subtract the numbers
=5x+15y-6
The distance of it away from zero cannot be a negative distance, distance is always positive therefor the absolute value will always be positive.
Short answer: no, absolute value is always positive
I hope this helps :)
