Answer:
2 min.
Step-by-step explanation:
1h is 60 min so divide 60 by 30 and you get 2
90x+120 is equivalent to 30 (3x+4)
The least number in the series is 59 I'm guessing sorry if it's wrong
Answer:
a. (3x^4 + 6 ) + (2x^2)
b. (X^3 ) + (-x -7)
c. (4.6x^4) + (-1.5x^2)
Step-by-step explanation:
For the first one, we have to write to polynomials, which equal 3x^4 + 2x^2 +6
One possible solution is (3x^4 + 6 ) + (2x^2)
For b, we can do,
(X^3 ) + (-x -7)
And finally for c, we can write,
(4.6x^4) + (-1.5x^2)
