complete the proof.

drag and drop the expression to correctly complete the proof of the polynomial identity

( x − y )^2 + 4xy = ( x + y )^2

i need you to simply solve the problem step by step for me to understand.

step-by-step explanation:

hope it's : )

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
