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.

Answer:
Hence Nell's mom Chocolate milk is more Chocolaty.
Step-by-step explanation:
Given:
Chocolate syrup used by Nell's mom = 30 ml
Amount of milk used = 2 ounces.
We will first find Amount of chocolate syrup used in 1 ounce of milk.
Now In 2 ounces of milk = 30 ml of chocolate syrup.
So in 1 ounce of milk = Amount of Chocolate syrup used for 1 ounce milk.
By using Unitary method we get;
Amount of Chocolate syrup used for 1 ounce milk=
Hence For every 1 ounce of milk Nell's mom uses 15 ml of chocolate syrup.
Also Given:
Chocolate syrup used by Nell's dad = 65 ml
Amount of milk used = 5 ounces.
We will first find Amount of chocolate syrup used in 1 ounce of milk.
Now In 5 ounces of milk = 65 ml of chocolate syrup.
So in 1 ounce of milk = Amount of Chocolate syrup used for 1 ounce milk.
By using Unitary method we get;
Amount of Chocolate syrup used for 1 ounce milk=
Hence For every 1 ounce of milk Nell's dad uses 13 ml of chocolate syrup.
Since The amount of chocolate syrup used by Nell's mom is more than Nell's dad.
Hence Nell's mom Chocolate milk is more Chocolaty.
