Foil (x+9)(3x-4) I have been stuck for ever
1 answer:
Answer:
Step-by-step explanation:
The foil method is used when multiplying 2 binomials. One is (x+9) and another is (3x-4). The steps of FOIL are:
- Multiply the first terms
- Multiply the outer terms
- Multiply the inner terms
- Multiply the last terms
- Combine like terms
Let's do the steps on our problem:
1. multiply x and 3x. So we have x * 3x = 3x^2
2. multiply x and -4. So we have x * -4 = -4x
3. Multiply 9 and 3x. So we have 27x
4. Multiply 9 and -4. So we have -36
Listing the terms, we have: 3x^2 -4x + 27x - 36
We combine like terms and have: 3x^2 + 23x - 36
That's our answer.

Using the monthly payments formula, it is found that a car with a value of at most $25,293.
<h3>What is the monthly payment formula?</h3>It is given by:
In which:
- P is the initial amount.
- r is the interest rate.
- n is the number of payments.
In this problem, we have that the parameters are given as follows:
A = 400, n = 70, r = 0.035.
Hence:
r/12 = 0.035/12 = 0.002917.
Then we have to solve for P to find the maximum value of the car.
P = $25,293.
