The answer to z would be 4
hope this helps :)
You need to categorize the similar terms with the same exponential.
Here, 3 terms can be categorized: x^3, x^2 and constant
Then you simply manipulate the coefficient:
(5-9)x^3 + (-7+4)x^2 + (6+1) = -4x^3 - 3x^2 + 7
Enter 5, then °/•, next the X, then 100, and finally = and you should get 5. OR you can turn 5°/• into decimal form of .05 and then press X , 100, and finally =. The answer is 5 either way.
Day = 8 4/5 ÷ 4
day = 44/5 ÷ 4
day = 44/5 × 1/4
day = 44/20
day = 11/5
day = 2 1/5
to be honest I dont know sorry
