Because this is a second degree equation you will have 2 solutions. When you take the square root of a number you have to account for both the positive and negative roots. Since the square root of 289 is 17 then your solutions are +17 and -17.
Answer:
$40
Step-by-step explanation:
25% is 1/4.
If 10 is 1/4 of the full amount, then you take 10 and multiply by 4 to get the full amount.
10 times 4 equals 40.
4.05 in a mixed number is 4 1/2
This answer is correct. The absolute value of a number is its distance from 0, and we are looking for an absolute value of 1. Both -1 and 1 are 1 whole number away from 0.
