When the negative is included in the parentheses, you end up with a positive product
Answer:
Answer in explanation
Step-by-step explanation:
Probability of Magic elf =
![p(elf) \times p(magic) \\ = \frac{1}{3} \times \frac{1}{5} \\ = \frac{1}{15} or \: 0.66667](https://tex.z-dn.net/?f=p%28elf%29%20%5Ctimes%20p%28magic%29%20%5C%5C%20%20%3D%20%20%5Cfrac%7B1%7D%7B3%7D%20%20%5Ctimes%20%20%5Cfrac%7B1%7D%7B5%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B1%7D%7B15%7D%20or%20%5C%3A%200.66667)
This is the concept of scale factors; The length of the larger figure will be calculated as follows;
linear scale factor=[length of larger figure]/[length of smaller figure]
plugging the values in the above formula we get:
let the length of the larger figure be x;
thus;
x/12=4/3
multiplying both sides by 12 to solve for x we get:
12*x/12=4/3x12
x=16
thus the length of the larger figure is x=16
