⇒ ![2t-3q](https://tex.z-dn.net/?f=2t-3q)
Step-by-step explanation:
Given expression:
![-3t+4q+5t-7q](https://tex.z-dn.net/?f=-3t%2B4q%2B5t-7q)
To write an equivalent expression:
Solution:
In order to write an equivalent expression, we will combine the like terms. By like terms, we mean the terms with the same variable constant.
For example :
and
are like terms.
We have:
![-3t+4q+5t-7q](https://tex.z-dn.net/?f=-3t%2B4q%2B5t-7q)
Combining like terms :
⇒ ![-3t+5t+4q-7q](https://tex.z-dn.net/?f=-3t%2B5t%2B4q-7q)
⇒ ![2t-3q](https://tex.z-dn.net/?f=2t-3q)
Thus, the equivalent expression can be given as:
⇒ ![2t-3q](https://tex.z-dn.net/?f=2t-3q)

Answer:
In 5040 ways.
Step-by-step explanation:
To solve this problem we will use combination without repetition which means:
C ( n k) = (n₁ k₁) (n₂ k₂) (n₃ k₃) = (4 3) (9 2) (7 3) =
(4 · 3 · 2 / 3 · 2 · 1) (9 · 8 / 2 · 1) (7 · 6 · 5 / 3 · 2 · 1) = 4 · 36 · 35 = 5040
It can be done in 5040 ways.
God with you!!!
