The answer is 6,889. Squared just means the number times itself. In this case, it's 83 x 83. :)
Use the formula
a_n = a_1•r^(n-1)
a_23 = 25•(1.8)^(23 - 1)

Answer:
3
Step-by-step explanation:
9 x (N + 2) = 45
9N + 18 = 45
9N = 27
N = 3
<span> If Jim has x football cards</span>
<span>He will have 5x baseballs cards</span>
Thus
<span> x + 5x = 120 >
total # of cards</span>
<span> 6x = 120</span>
<span> x= 120/6 =
20</span>
<span> so Jim has 5x
baseball cards = 20*5 =100 baseball cards</span>
