Answer:
x² + 2ax + a² + 5x + 5a + 4
Step-by-step explanation:
Formula -
( a + b )² = a² + 2ab + b²
Steps -
( x + a )² + 5 ( x + a ) + 4
x² +2ax + a² + 5 ( x + a ) + 4
x² + 2ax + a² + 5x + 5a + 4
The smaller the magnitude of the correlation, the weaker the correlation. The magnitude of -0.25 is 0.25, the smallest correlation magnitude.
400 * 2% = 8
A: 8 * 6 = $48
B: 400 + 48 = $448
