Bella has 40 coins, all nickels and quarters, worth $7.60. How many nickels and how many quarters does she have

i wish i could you, i have no idea how to answer this

step-by-step explanation:

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.

2,160 π
