Answer:
2nd option
Step-by-step explanation:
Express the sum of the 2 polynomials by removing the parenthesis , so
5 - 2x³ + x + 4 - 3 + 2x³ - 5x ← collect like terms
= 9 - 3 - 4x
82/146 = x/18 cross multiply and x= 6 so 6 gallons.
If x=6 and y=3 is 9_______________________________________
Answer:
f(x) = 6x² -25x -9
Step-by-step explanation:
6x² - 25x -9 = (2x - 9) (3x + 1)
x = (2/9) or (- 1/3)
