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.
Answer:
1. 0.875 2. 0.666… 3. 2.25 4. 0.8333…
Step-by-step explanation:
The easiest way to convert a fraction to a decimal is to divide the numerator (the top of the fraction) by the denominator (the bottom of the fraction) by using a calculator. The resulting answer will be the value of the fraction expressed as a decimal number. Hope you get it! :)
-5+|9-11|
first, you would find the absolute value
|9-11|= |-2|=2
then the problem looks like this
-5+2= -3
So, the answer is negative three
