Explain how to multiply 12 and 6x .

you can't because 6 has an x and 12 does not so you have your answer 12+6x

72x

Step-by-step explanation:

we can multiply the coefficient of x with 12.

The coefficient of x is 6

now,

12*6=72

72 is the final coefficient of x i.e. 72x

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
