A(n) = 16 + 8(n - 1)
A(16) = 16 + 8(16 - 1)
A(16) = 16 + 120
A(16) = 136 people
The sum of a number and its additive inverse is equal to zero. The correct option among all the options that are given in the question is the second option or option "b". If we assume "x" to be a real number, then its additive inverse is "-x". On adding these two, we can see that the result comes to zero.
Answer:
s for length of either equal side
b for the unequal side
b=-2+2*(s+s) and 2s+b=40
b=2*2s-2
b=4s-2
2s+4s-2=40
6s-2=40
6s=42
s=7
b=4*7-2
b=28-2
b=26
it would be 3 because when you add it, it gets to be 932 and the tens place is 3.
