-2x³ + 3 = -x³ - x² + x + 1
Add x³ to both sides, and subtract 3 from both sides.
-2x³ + x³ = -x² + x + 1 - 3
Add like terms.
-x³ = -x²+ x - 2
Move all of the (X's) to both sides, by adding x² to both sides, and subtracting x form both sides.
-x³ + x² - x = -2

Answer:
2100 second
Step-by-step explanation:
4:30 pm to minutes
4 × 60 + 30 = 240 + 30
= 270 minutes
5:05 to minutes
5 × 60 + 5 = 300 + 5
= 305
4:30 to 5:05
305 - 270
= 35 minutes
35 minutes to second
35 × 60
= 2100 second
