Answer:
165
Step-by-step explanation:
formula is
nCr = n!/(r!(n−r)!)
r= 8 = number of choosing objects from the set
n = 11 = total number of objects in the set
C(n,r)=C(11,8)
=11!/(8!(11−8)!)
! means factorial
factorial means to multiply by decreasing positive numbers.
For example, 8! = 8 ∗ 7 ∗ 6 ∗ 5 ∗ 4 ∗ 3 ∗ 2 ∗ 1 = 40320
=11!/8!×3!
= 165

VW = VC + CW
61 = z + 13 + z + 8 = 2z + 21
2z = 61 - 21 = 40
z = 40/2 = 20
z = 20.
50 x 3/10 = 15
12 x 2/3 = 8

15+8=23 lbs
Answer:
the answer of given question is -1/5
F(x)=x-5
g(x)=x^2
Now adding f(x) and g(x)
x-5+x^2-1
x^2+x-6
x^2+(3-2)x-6
x^2+3x-2x-6
x(x+3)-2(x+3)
(x-2)(x+3) answer
