B is the closet to pi hsiebfjwjgsbe9fbe
Answer:
x ≈ - 9.41, x ≈ - 6.59
Step-by-step explanation:
Given
x² + 16x + 62 = 0 ( subtract 62 from both sides )
x² + 16x = - 62
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(8)x + 64 = - 62 + 64
(x + 8)² = 2 ( take the square root of both sides )
x + 8 = ±
( subtract 8 from both sides )
x = - 8 ± 
Hence
x = - 8 -
≈ - 9.41
x = - 8 +
≈ - 6.59
Answer:
The expressions are equivalent
Step-by-step explanation:
We can start by simplifying the first expression:
1.25x+4+0.75x-3
Move like terms so that they are together:
1.25x+0.75x+4-3
Now, combine like terms:
2x+1
The expressions are equivalent
