3 sqrt(20) -3 sqrt(45) + 5 sqrt(12)

3 sqrt (4*5) - 3 sqrt(9*5) + 5 sqrt(4*3)

3 sqrt(4) *sqrt(5) - 3 sqrt(9)sqrt(5) + 5sqrt(4) sqrt(3)

3*2 sqrt(5) - 3*3*sqrt(5) +5*2*sqrt(3)

6 sqrt(5) -9sqrt(5) +10sqrt(3)

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
