3√x+2 = √x+4

divide both sides by 3

√x+2 = √x+4 / 3

remove radical by squaring both sides

x+2 = x+4/9

x+2 = x/9 + 4/9 =

8x/9 = -14/9

8x*9 = -14*9=

72x = -126

x = -7/4

gavmur [86]

Answer:

450

Step-by-step explanation:

A = P(1 + rt)

A = final amount

P = initial principal balance

r = annual interest rate

t = time(in years)

Given,

P = 3000

t = 2 years

r = 7.5% = 7.5/100 = 0.075

A = 3000(1 + 0.075*2) = 3450

Interest = 3450 - 3000 = 450
