1. b³ + 8 = ___ + ( 2 ) ³
= ( b + 2 ) ( ___ - ( b ) ( 2 ) + ( 2 ) ²]
= ___ ( b² - ___ + ___ )
2. y³ - 27 = ( y )³ - ___
= ___ [( y )² + ___ ( 3 ) + ( __ )
= ( y - 3 ) ( y² + ___ + ( y )²]
3. 64׳ - y³ = ___ - ( y )³
= ( 4× - y )] ( 4× )² + ____ + ( y )²]
= ___ ( ___ + 4xy + ( ___ )

Verified answer
1. b³ + 8 = (b)³ + (2)³
= (b + 2)[b² - (b)(2) + (2)²]
= (b + 2)(b² - 2b + 4)
_____________________
2. y³ - 27 = (y)³ - (3)³
= (y -3)[(y)² + (y)(3) + (3)²]
= (y - 3)(y² + 3y + 9)

3. 64x³ - y³ = (4x)³ - (y)³
= (4x - y) [(4x)² + 4xy + (y)²]
= (4x - y)(x² + 4xy + y²)

Step 1: Are the inequalities in the form y = mx + b? If yes check the column, if no, transform. Linear Inequality Yes No Transform y < 2x+2 2x + 4y 22 Step 2: Complete the table. Slope rise run Type of Line to be used Linear Inequality y< 2x+ 2 2x + 4y > 2 Step 3: Graph and then shade the region. Use graphing paper. Choose ? points and check if it is included in the solution set.
