Step-by-step explanation:
- P = 2 (2x+7) + 2(3x +4)
- Now, comparing the above with 62 we get x=4
- Length is 16 and width is 15
This is a combination problem. The approach to this is by using the nCr method, where n is the number of total objects and r is the number of success. For example, if you want to get 3 red out of the total 4, then that would be 4C3. That means,
4C3 = 4!/3!(4 - 3)! = 4 ways
If you want to get 2 green out of the total 6, then that would be 6C2. That means,
6C2 = 6!/2!(6-2)! = 15 ways
Therefore, there are a total of 4+15 = <em>19 ways</em>.
Your answer would be 95 calories per apple
That looks right if all you were doing was finding how many more you needed than it should be good
