they are saying x = 3 so you would use the middle equation
so -4x becomes -4(3)
-4 * 3 =-12
Step-by-step explanation:
(x+2y)(x-2y)
- x^2-2xy+2xy-(2y)^2
- x^2-4y^2
The distance between is (8,6).
Thing is, you didn't give us the choices!
1/3 is equal to 4/12.
1 goes into 3, 3 times, and 4 goes into 12 three times. Therefore 4/12 is also 1/3.
