Answer:
7y4-28y3
Step-by-step explanation:
First you change the formation of the equation, so it looks like -7y3(-y+4). You use distributive property and when distribute the answer will be 7y4-28y3. Hope this helps!
0.72 repeating is the sum of a geometric series with first term 0.72 and common factor 1/100. The sum is given by:
(first term) 0.72 0.72 72
--------------------------- = --------------- = ------------ = ------------
1 - common factor 1 - 1/100 99/100 99
This 72/99 can be reduced to 8/11.
0.72 repeating can be rewritten as the fraction 8/11.
The missing number would be 100.
e.g 400/2= 200
200/2= 100
100/2 = 50
50/2 = 25
-1/6 The x is coefficient is negative and is 1/6
