Using the triangle of pascal we have that the expression equivalent to (x + y) ^ 6 is given by:
x ^ 6 + 6x ^ 5y + 15x ^ 4y ^ 2 + 20x ^ 3y ^ 3 + 15x ^ 2y ^ 4 + 6xy ^ 5 + y ^ 6
Therefore, the coefficients of the expansion are given by:
1, 6, 15, 20, 15, 6, 1
Answer:
The coefficients corresponding to k = 0, 1, 2, ..., 6 in the expansion of (x + y) ^ 6 are 1, 6, 15, 20, 15, 6, 1
Assuming the numbers are percents, the answer is 25%, because 5/20 is 1/4, then convert the fraction to a percentage and you get 25%.
Answer:
Length is 20 m and width is 4 m.
Step-by-step explanation:
Given:
Perimeter of the rectangular alley, 
Length is 5 times the width.
Let width be 
.
So, as per question,
Length,
Now, perimeter of rectangle is given as:
Plug in 48 for 
, 
for 
and for b.
Therefore, width is 4 m.
Length is 
m.
Answer:
2/8 and 3/12
Step-by-step explanation:
You multiply both the numerator and denominator by the same number to get equivalent fractions.
1 x 2
4 x 2
= 2/8
and
1 x 3
4 x 3
= 3/12
(x+1)(x+2)
this is what i got hope it helps
