Answer:
3x+36
Step-by-step explanation:
(3•x)+(3•12)
3x+36
Answer:
quotinet = 3x² - 2x - 2
remainder = 7
Step-by-step explanation:
12x³ - 2x² - 12x + 3
= 3x²(4x + 2) - 6x² - 2x² - 12x + 3
= 3x²(4x + 2) - 8x² - 12x + 3
= 3x²(4x + 2) - 2x(4x + 2) + 4x - 12x + 3
= 3x²(4x + 2) - 2x(4x + 2) - 8x + 3
= 3x²(4x + 2) - 2x(4x + 2) - 2(4x + 2) + 4 + 3
= 3x²(4x + 2) - 2x(4x + 2) - 2(4x + 2) + 7
= (4x + 2)(3x² - 2x - 2) + 7
so
quotinet = 3x² - 2x - 2
remainder = 7
Answer:
it would be A
Step-by-step explanation:
Answer:
The answer to 9 is below
Step-by-step explanation:
2(L + W) = P
2(W + 5a - b) = 16a + 2b
2(W + 5a - b) = 2(8a + b)
W + 5a - b = 8a + b
W = 3a + 2b
Answer:
x ≈ - 6.74, 0.74
Step-by-step explanation:
x² + 6x - 5 = 0 ( add 5 to both sides )
x² + 6x = 5
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(3)x + 9 = 5 + 9
(x + 3)² = 14 ( take square root of both sides )
x + 3 = ± 
( subtract 3 from both sides )
x = - 3 ±
Then
x = - 3 - ≈ - 6.74 ( to the nearest hundredth )
x = - 3 + ≈ 0.74 ( to the nearest hundredth )
