Have to be positive on answer i cant fail this test i just need 2 give you a metal 1. (–10x3 + 30x – 20) ÷ (–5x + 5) (1 point)2x2 – 2x + 4 –2x2 – 2x – 4 –2x2 + 2x + 4 2x2 + 2x – 4 2. the width w of a rectangular swimming pool is x + 4. the area a of the pool is 2x3 – 29x + 12. what is an expression for the length of the pool? (1 point)2x2 + 8x +3 2x2 – 8x – 3 2x2 – 8x + 3 2x2 + 8x – 3

                      2x²  +2x  -4
         
-5x+5I -10x³ +0x² +30x -20
           -10x³ +10x²
         
                    -10x³+30x
                    -10x² +10x
                 
                              20x-20
                              20x-20
                             
                                        0
The answer for question #1 is  D,   2x²  +2x  -4

Use the same method to find answer for #2. The answer I got is 2x²-8x+3, C
