Please help and explain how u solve this

∛x² + ∛xy +  ∛y²

Step-by-step explanation:

Let me give it a try

x =( ∛x)³

y =( ∛y)³

x-y = ( ∛x)³ - ( ∛y)³

Basic formula for a³ - b³ = (a - b)(a² + ab + b²)

x-y = ( ∛x)³ - ( ∛y)³ = (∛x - ∛y)(∛x² + ∛xy +  ∛y²)

(x - y) / (∛x - ∛y) = ∛x² + ∛xy +  ∛y²

step-by-step explanation:

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
