x = 6
Step-by-step explanation:
Let's assume x is the variable. There are 3 pairs of pants, hence the 3. The total fee is 18, hence the 18.
Answer:
a = 249 and b = 1.16
Step-by-step explanation:
Consider the provided information.
The exponential function for growth is: 
Here, a is the initial value and r is the rate of change.
It is given that the number of birds is 249.
It means a = 249
The rate is given 16%
r=0.16
Put the value of a and r in the above formula.


Now we will compare it with the exponential function form 
Therefore, a = 249 and b = 1.16
Answer:
1) 10mn - 10×m×n
2)15m - 15×m
10×m×n×+15×m
=10mn+15m
factorize
common number(divisor) = 5
5m(2n+3)
5m*2n=10mn
5m*3=15m
The answer would be D....
