Answer:
(3x -1) (3x+1)
Step-by-step explanation:
9x^2 - 1
Rewriting
(3x)^2 -1^2
This is the difference of squares a^2 -b^2 = (a+b) (a-b)
(3x -1) (3x+1)
FV=PV(1+r)ⁿ
FV=Future Value, or the $2,600 that you want.
PV=Present Value, or the value that you are depositing.
APR: .06
2,600=2,000(1.06)ⁿ
2,600=2120ⁿ
It would take about a year for Nicole to get $2600.

Your answer is 4 radical 2.
Let t, h, b represent the weighs of tail, head, and body, respectively.
t = 4 . . . . given
h = t + b/2 . . . . the head weighs as much as the tail and half the body
b/2 = h + t . . . . half the body weighs as much as the head and tail
_____
Substituting for b/2 in the second equation using the expression in the third equation, we have
... h = t + (h + t)
Subtracting h from both sides gives
... 0 = 2t . . . . . . in contradiction to the initial statement about tail weight.
Conclusion: there's no solution to the problem given here.
