Answer:
C=252
Step-by-step explanation:
Given:
x^5y^5
(x+y)^10
Find the coefficient of x^5y^5
To get the coefficient of x^5y^5,
we will put r = 5, in the below given general term.
The general term is : nCr =x^ry^n-r
We get:
Coefficient is = 10C5
= 10!/5!*5!
= 252
The coefficient of x^5y^5 is 252
C. 252
One <em>possible answer</em> is:
9×(2+3)
Explanation:
First we find the sum of 18 and 27. 18+27 = 45.
Next we find the GCF of 18 and 27. We do this by finding the prime factorization of each:
18 = 2*9
9 = 3*3
Thus, 18 = 2*3*3.
27 = 3*9
9 = 3*3
Thus, 27 = 3*3*3
We want the common factors; there are 2 3's in common, so 3*3 = 9 is the GCF. This makes the product 9×( ). The missing number would be 5, since 9*5 = 45. Writing this as a sum, we can use 2+3; this gives us 9×(2+3).
4 x 4 x 4 x 4 x 4
I think that’s the answer
1. percent increase : (new number - original number) / (original number)...x 100
<span>(22 - 20) / 20 = 2/20 = 0.1.....0.1 x 100 = 10...so there is a 10% increase</span>
