Answer:

385 balas de cañon

Step-by-step explanation:

la base mide 10 x 10 = 100 balas de cañon

la capa siguiente mide 9 x 9 = 81 balas de cañon

la siguiente 8 x 8 = 64

despues 7 x 7 = 49

luego 6 x 6 = 36

y seguimos adelante con 5 x 5 = 25, 4 x 4 = 16, 3 x 3 = 9, 2 x 2 = 4 y finalmente tenemos 1 sola bala de cañon.

El total de balas de cañon = 100 + 81 + 64 + 49 + 36 +25 + 16 + 9 + 4 + 1 = 385 balas de cañon

3n-5=-48-40n. Please help . I need the steps to solve and the answer
liraira [26]

3n-5=-48-40n

Move -40n to the other side. Sign changes from -40n to +40n.

3n+40n-5=-48= -48-40n+40n

3n+40n-5=-48

Move -5 to the other side.

3n+40n-5+5=-48+5

3n+40n=-43

43n=-43

Divide by 43 for both sides

43n/43=-43/43

n=-1

Answer: n=-1
