First let us find the length of JN
JN =JK +KN
JN = 82+105 = 187
JN=187..............(1)
UC= JN -( JH +HU+CN)
We are given :
JH= 22, HU = 96 and CN = 51
plugging all the values we get
UC = 187-( 22+96+51)
UC =187 -169
UC = 18
Answer is UC =18 ( option B)
Answer:
2(n-9)
Step-by-step explanation:
Hi there!
Let "a number" = n.
"The difference" translates to subtraction, so when the question tells us "the difference of a number and 9", it translates to "n-9".
"Twice" means we'll be doubling something. In this case, we're doubling "n-9":
2(n-9)
I hope this helps!
Answer:
126
Step-by-step explanation:
n! / (r! (n-r)!)
In this case n = 9 and r = 4
9!/ (4! * (9-4)!)
9!/ (4! * 5!)
= 126
9! = 9x8x7x6x5x4x3x2x1
6-4(2/3)
5(3/3)-4(2/3)
1(1/3)
