I am not completely sure but 2.7 because I subtracted the 6 8/9 by 6 4/9 and got 8/3 which then I dived and got 2.66666666666667
Just work this problem out backwards. First write out an equation.
(x+4)•3=30
Now solve :
(x+4)•3=30
3x+12=30
-12 -12
3x=18
/3 /3
x=6
Your answer is 6!

Answer:
can u zoom in and take picture
Step-by-step explanation:
(2x³ - 5x² + 8)(x + 3) = ?
First step is to distribute.
2x^4 + 6x³ - 5x³ - 15x² + 8x + 24
Now combine like terms.
2x^4 + x³ - 15x² + 8x + 24
This is your answer, since you can't simplify any further or solve it without some more information.
