Answer:
9x^4+3x^2 -6
Step-by-step explanation:
(3x^2-2)(3x^2+3)
expand to remove the bracket
9x^4 + 9x^2 -6x^2 - 6
9x^4 + 3x^2- 6
315+210 =525 525+210=735 735+210=945
after 7 hours of work they have earn 945
any question ?
The value of k should equal to 4/3. You can multiply k on each side to get 4=3k and divide by 3 to get 4/3=k. Another approach is to reciprocate the RHS and LHS of the equation to get k/4=1/3, and then multiply by 4 on each side to get k=4/3.
