|4x + 4| = 15
First, let's get rid of the absolute value signs to get the first solution.
4x + 4 = 15
Subtract 4 from both sides
4x = 11
Divide each side by 4
x = 11/4 or 2.75
Now, let's get the solution by changing 15 to -15.
4x + 4 = -15
Subtract 4 from both sides
4x = -19
Divide both sides by 4
x = -19/4 or -4.75
Answer: D. -3x+9i)(x+3i) i hope this helped :)
Recall that
is only defined for
, and under this condition we have that
. But 1.7 > 1, so
is not a real number.
