B, g(n) = 50*1.15^n
Step-by-step explanation:
It's a geometric sequence because the money is increasing by a percentage every year.
Answer:
x^2+29x+210
I hope this helps! I did this through the FOIL method. :)
The little lines on each side of the rhombus mean that all the sides are the same length.
We can set line LM and MN equal to solve for X, then we can solve the length of a side.
3x-3 = x+7
Add 3 to each side:
3x = x +10
Subtract x from each side:
2x = 10
Divide both sides by 2:
x = 10/2
x = 5
Now we have the value for x, replace x in one of the side formulas:
x +7 = 5+7 = 12
Each side = 12 units.
The perimeter would be 12 + 12 + 12 + 12 = 48 units.
