Recall the binomial theorem.
1. The binomial expansion of 
is
Observe that
When we multiply these by 
,
• 
and 
combine to make 
• 
and 
combine to make 
and the sum of these terms is
2. The binomial expansion is
We get the 
term when 
:
Answer:
226.19
Step-by-step explanation:
pi * r^2 = area
The radius = diameter/2 = 6
pi * 6^2 * 2 = area of 2 tortillas
72pi = area of 2 tortillas
That rounds to 226.19
Answer:
x is less than -3
Step-by-step explanation:
3x^2+9x<0
x^2+3x<0
x(x+3)<0
x+3<0
x<-3
Answer:
7/8 > 5/6
Step-by-step explanation:
A) 7/8
We can compare this as follows.
Lets say both are equal.
Cross multiplying these we get 40=42
We get 40<42. In fraction we get
In case if you want to convert this to decimal, we get;
5/6 = 0.833 and 7/8 = 0.875
We get 5/6<7/8
B) 4/5
Similarly we get 4/5 = 0.8 and 5/6 = 0.833
Here 4/5<5/6
C) 3/4
we get 3/4 = 0.75 and 5/6 = 0.833
3/4<5/6
D) 2/3
we get 2/3 = 0.66 and 5/6 = 0.833
2/3<5/6
Step-by-step explanation:
