7. This dang do did. So do so did is
Answer:
c.9
the correct answer
semoga jawapan ini membantu
3(x+4)-10 = 1/10 (4x+16)
3x+12-10 = 1/10*2 (2x+8)
3x+2 = 1/5* (2x+8)
3x+2 = 2/5x + 8/5
15x+10 = 2x+8
15x-2x=8-10
13x = -2
x = -2/13
She made her mistake when she forgot about the 1/10 and didn’t include it
Answer:
see explanation
Step-by-step explanation:
(1)
Given
- 2x = x² - 6 ( subtract x² from both sides )
- x² - 2x = - 6 ( multiply through by - 1 )
x² + 2x = 6
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(1)x + 1 = 6 + 1
(x + 1)² = 7
(2)
Take the square root of both sides
x + 1 = ± ( subtract 1 from both sides )
x = - 1 ±
Solutions are x = - 1 - , x = - 1 +
