Answer:
Step-by-step explanation:
72 is the product of 8 and 9, so the number needs to be divisible by both 8 and 9.
The number 100 is divisible by 8 with a remainder of 4, so to make it have no remainder, we must add another 4 to the number: 104. We cannot have any other digit in the ones place (x) and have 10x be divisible by 8.
The 4-digit number must have a sum of digits that is divisible by 9 if it is to be divisible by 9. 104 has a sum of digits of 5, so we must have another digit of 4 to get a number divisible by 9. There is no other single digit that will do.
The number we're looking for is 4104 = 72·57. There are no other solutions.
Answer: 3x -2
Because i know as soon as the line goes through the y-axis that number is your y-intersect and for the slope from the first point to the second point you go up 3 and over 1 and 3/1 is equal to 3 which gives your answer y=3x-2
Answer:
4 feet
Step-by-step explanation:
Let the side length of the square be x feet.
