D. Y is negative and x is positive, so that means either B or D. Since y is negative, SUBTRACTING five would make a more negative number. So you want D.
Greatest common factor of 42, 98, and 14 is 14
The factors of 14 are: 1, 2, 7, 14
The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42
The factors of 98 are: 1, 2, 7, 14, 49, 98
Then the greatest common factor is 14.
Because the number you provided is negative, we won't get a real answer instead a complex answer.
Now simplify the square root.
To simplify a square root, find two factors where one of the factors is a perfect square.
Let the number be x:
3*x-2=13
∴3x=13+2
∴3x=15 (divide both sides by 3)
∴x=5 the answer is C
-27. But I am not certain, so I am very sorry for mistake if
