Step-by-step answer:
We are looking at the coefficient of the 22nd term of (x+y)^25.
Following the sequence, first term is x^0y^25, second term is x^1y^24, third term is x^2y^23...and so on, 22nd term is x^21y^4.
The twenty-second term of (x+y)^25 is given by the binomial theorem as
( 25!/(21!4!) ) x^21*y^4
=25*24*23*22/4! x^21y^4
= 12650 x^21 y^4
The coefficient required is therefore 12650, for a binomial with unit valued coefficients.
For other binomials, substitute the values for x and y and expand accordingly.
Question would have been more clearly stated if the actual binomial was given, as commented above.
Answer:
x = 5
Step-by-step explanation:
Answer:
0
Step-by-step explanation:
Step-by-step explanation:
here,
x°+15°=5x°-41°[being vertically opposite angle]
15°+41°=5x°-x°
56°=4x°
thus,x=14°
<h3>hence,the value of x is 14°.</h3><h2>I hope this will help you.</h2><h2>please mark my answer as BRAINLIEST if you liked it....</h2>
b, but I'm not sure. this could very easily be incorrect. you may need to look this up on google first.
