"you rent four movies and return them a day late. the regular rental fee is xdollars per movie. you are charged a total of (4x+8) dollars. a. factor the expression using the cake method (+8) = don't put spaces when you type your answer. b. the fee for returning a movie 1 day late is $"

Step-by-step explanation:

Let's call the amount of dollars per movie.

The following expression represents charges in dollars:

If we use the cake method, it would be like the following:

    | 4    8

2  | 2    4

2  | 1     2

So, the Greatest Common Factor is 2 times 2, which is 4. GCF = 4.

a. The factored expression would be:

Notice that the charge per movie is $(x+2), because the factor 4 represents the total number of movies.

Therefore, in this case, the fee per movie is x + 2. (b).

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
