X=4
Explanation
First subtract 4x^2 + 6x from both sides of the equation
X^2 - 8x + 16 = 0
Then let’s factorice the equation using the middle-term break:
x^2 - 4x - 4x + 16 = 0
x (x - 4) - 4 (x - 4) = 0
(x - 4) (x - 4) = 0
(x - 4) ^2 = 0
x = 0
Therefore the solution to the equation is x = 4
Answer:
x = 15
Step-by-step explanation:
since two lines are parallel,
3x + 45 = 2x + 60 (Being alternate angle)
or, 3x - 2x = 60 -45
x = 15

Answer:
Option C: (4.47,-0.46)
Step-by-step explanation:
To convert Cartesian coordinates into polar coordinates , use the following formulas:
Therefore:
Because (4,-2) is located in Quadrant II, the angle must also be located in Quadrant II. Therefore, the correct polar coordinate would be (4.47,-0.46)
