I hope this helps you
distance is X
motorcycle 60 mph and times is t
minivan 50 mph and times is t+1
X=60.t
X=50(t+1)
60t=50t+50
10t=50
t=5 hour
t+1=6 hour
We use the trinomial theorem to answer this question. Suppose we have a trinomial (a + b + c)ⁿ, we can determine any term to be:
[n!/(n-m)!(m-k)!k!] a^(n-m) b^(m-k) c^k
In this problem, the variables are: x=a, y=b and z=c. We already know the exponents of the variables. So, we equate this with the form of the trinomial theorem.
n - m = 2
m - k = 5
k = 10
Since we know k, we can determine m. Once we know m, we can determine n. Then, we can finally solve for the coefficient.
m - 10 = 5
m = 15
n - 15 = 2
n = 17
Therefore, the coefficient is equal to:
Coefficient = n!/(n-m)!(m-k)!k! = 17!/(17-5)!(15-10)!10! = 408,408
(7) is the greatest common factor of 56 and 49
Answer:
The answer is... the first option... why equals negative x + 5 and y = x - 3
