Which are equivalent expressions? Check all that are true.
2x + 6x + 12x = 2(x + 3x + 6x)
3x + 8y = 3(x + 2x)
7x + 6y = 42xy
9x + 2y = 2(4x + y)
11x + 22y = 11(x + 2y)

For what value of x does 4x = (1/8) x + 5?

The equation of a circle is (x - 3)2 + (y - 7)2 = 25. determine the length of the radius. 4 25 12.5 5 write the standard equation of the circle with center (2, 3) and a diameter of 12. (x - 2)2 + (y - 3)2 = 36 (x + 2)2 + (y + 3)2 = 12 (x - 2)2 + (y - 3)2 = 6 (x - 3)2 + (y - 2)2 = 36 the equation of a circle is (x + 3)2 + (y + 7)2 = 25. where is (3, 4) located in relation to the circle? on the circle in the interior of the circle in the exterior of the circle at the center of the circle

What is the solution of the systems of equations? y=2/3x+3 x=-2
