The value of an initial investment of $400 at 3% nominal yearly interest compounded quarterly can be
modeled using which of the following equations, where I is the number of years since the investment was
made?

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

6 and 24

step-by-step explanation:

6 x 4 = 24
