<h3>
Answer: 0</h3>
Explanation:
The single digits are {0,1,2,3,4,5,6,7,8,9}
So naturally 0 is the first thing to test.
The number 270 is a multiple of 9 because 9*30 = 270. The digits of 270 add to 2+7+0 = 9 showing that it's a multiple of 9. Refer to the "divisibility by 9 rule".
The next possible value of y will be 9 units higher than y = 0, so we go for y = 9. Meaning that 279 is also a multiple of 9 (because 2+7+9 = 18 is a multiple of 9).

Answer:
0 real solutions
Step-by-step explanation:
This problem can be solved by simply looking at the sign in front of 89. Since it is a negative, nothing squared can equal it.
In other words, when a number is squared, the product will never be negative. This is because even when two negatives are multiplied by each other, the negatives cancel each other out.
Examples:
2^2 = 4
-2^2 = 4 (not -4)
The correct and best answer is r=320 because you have to divide both sides by 0.3
