If the polynomial 6x ^ 6 - 4x ^ 5 + 9x - 6 is to be factored by grouping , which step should be taken?
a) factor 2 from 6x ^ 6 - 4x ^ 5

b) factor from 6x ^ 6 - 4x ^ 5 + 9x

c)factor from 6x ^ 6 - 4x ^ 5 + 9x .

d) factor 2x ^ 5 from 6x ^ 6 - 4x ^ 5 and 3 from 9x - 6 .

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
