You would write the 80.5 on the outside 418.6 on the inside. You can't divide by a decimal so you have to move the decimal point as many times as you need to on the outside number. You only have to move it over once in the80.5 so it is now 805. You do the same thing to the inside so it it is 4186. You are now dividing 4186 by 805. The answer is 5.2
Q2) 58.08
Q3) I got 180 but not sure.
Q4) I got 138
Q5) I got 28.56 for this one.
Hope this helps.
Answer:
5(2x^5 + x^2 - 3)
Step-by-step explanation:
The only factor in common is 5, so you would have 5(2x^5 + x^2 - 3). That can't be factored further. IF the equation had been to the fourth degree on the first term rather than to the fifth degree, it could have been factored as 5(2x^2 -3)(x^2 +1).
Equal to 4.73 repeating, rounded is 4.7
