Answer:
-6(3x +2) = 2x -5 -20x -7 (use the distributive property )
-18x -12 = -18x - 12 (i combined like terms on the right side of the equation)
at this point I can tell that it's true for any value of x, so they all apply
Step-by-step explanation:
Answer:
x ≈ - 6.49, x ≈ 12.49
Step-by-step explanation:
Given
(x - 3)² + 7 = 97 ( subtract 7 from both sides )
(x - 3)² = 90 ( take the square root of both sides )
x - 3 = ±
( add 3 to both sides )
x = 3 ± 
Then
x = 3 -
≈ - 6.49 ( to the nearest hundredth )
x = 3 +
≈ 12.49 ( to the nearest hundredth )
