The fourth term of the binomial expansion 
can be calculated using the formula for (i+1)-th term of the binomial expansion:
In order to find term 
, determine that
Now
Answer: correct choice is A
Answer:
l=6
b=30
Step-by-step explanation:
b=5l
perimeter= 72
2(l+b)= 72
l+b= 36
l+5l= 36
6l= 36
l= 6
b=5l= 6*6= 30
Answer:
60 nickels
70 dimes
Step-by-step explanation:
convert $10 to cents
$10 = 1000 pennies
1000 = 5x + 10 (x+10)
1000 = 15x + 100
900 = 15x
x = 60
60 nickels
70 dimes
check to be sure this adds up to $10
The answer is: 36
Because, bisecting the base of the triangle gives of two segments of five. This forms two triangles with base of 5 and altitude (in this case height) of 12. There exists a special pythagorean triplet triangled named 5-12-13 meaning if you have a right triangle with two of these sides then the unknown side is the number left out. In this case, the altitude forms a right angle on the base which allows the sides of the big isocs. triangle to be 13 giving us 13 + 13 + 10 to be the perimeter = 36.
The answer is 32x+8
