Full process to find HCF of x^3 -1 and x^4+ x^2 + 1

Step-by-step explanation:

Factor of x^3-1= (x-1)(X^2+X+1)

Apply the formula of a^3-b^3=(a-b)(a^2+b^2+1)

X^4+x^2+1=(x^2+X+1)(x^2-x+1)

H.c.f is (x^2+X+1)

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
