That would simplify to 32x^5+400x^4+200x^3+5000x^2+6250x+3125
You would do that because you have to write it repeatedly as (2x+5)(2x+5) and so on.
The two numbers are (9+ 5√5)/2 and (9- 5√5)/2.
(9+ 5√5)/2+ (9- 5√5)/2= 9
(9+ 5√5)/2* (9- 5√5)/2= -11
Hope this helps~
Answer:
(69)(3)−8
=
15
199≠15
False
Step-by-step explanation:
hope it helps, 69(3) is already bigger than 15, then -8 makes it 199, which is definitely not equal to 15.
The equation would be 400+20c per week so if you do that equation, to figure it out 680-400=280 and then you would divide it by 20 and whatever that answer is, in this case it would be 14.
