What is the simplified form of (x – 2)(2x +3)? Use the Distributive Property.

2x2 – x – 6
2x2 – 6
2x2 – 7x – 6
2x2 + x – 6
2. What is the simplified form of (3x + 2)(4x – 3)? Use a table.
12x2 + 18x + 6
12x2 + x – 6
12x2 + 18x – 6
12x2 – x – 6
3. What is the simplified form of (4p – 2)(p – 4)?
4p2 + 6p – 16
4p2 – 18p + 8
4p2 – 14p – 6
4p2 – 6p + 16
4. The radius of a cylinder is 3x – 2 cm. The height of the cylinder is x + 3 cm. What is the surface area of the cylinder? Use the formula A = 2r2 + 2rh.

Answered by wiki @



1) (x – 2)(2x +3) = 2x²+3x-4x -6
the answer is 
2x² – x – 6
2) 
(3x + 2)(4x – 3) =12x²-9x +8x -6
the answer is 
12x2 – x – 6
3) 
(4p – 2)(p – 4) = 4p²-16p-2p+8
the answer is 
4p2 – 18p + 8
4) since 
A = 2r2 + 2rh
so 
A = 2(3x – 2)² + 2(3x – 2)(x + 3)
        = 
(3x – 2) ( 2(3x – 2) + 2 (x + 3))
A =(3x – 2) ( 10x+2)
