Step-by-step explanation:
![18 {u}^{2} - 50y \\ \\ = 2[9 {u}^{2} - 25y] \\ \\ = 2[(3 {u})^{2} - (5 \sqrt{y} )^{2} ] \\ \\ = 2(3u + 5 \sqrt{y} )(3u - 5 \sqrt{y} )](https://tex.z-dn.net/?f=18%20%7Bu%7D%5E%7B2%7D%20%20-%2050y%20%5C%5C%20%20%5C%5C%20%20%3D%202%5B9%20%7Bu%7D%5E%7B2%7D%20%20-%2025y%5D%20%20%5C%5C%20%20%5C%5C%20%20%3D%202%5B%283%20%7Bu%7D%29%5E%7B2%7D%20%20-%20%285%20%5Csqrt%7By%7D%20%29%5E%7B2%7D%20%5D%20%20%20%5C%5C%20%20%5C%5C%20%20%3D%202%283u%20%20%2B%205%20%5Csqrt%7By%7D%20%29%283u%20-%205%20%5Csqrt%7By%7D%20%29)
You would have 60 different types of pens with this brand. You need to multiply 12 and 5 (because you have 12 different colors for every type of tip, so you have 5 groups of 12).
Answer:
His nephew is 13
Step-by-step explanation:
Reverse the given process,
32 - 6 = 26,
26 ÷ 2 = 13,
The answer is 13.
First, you must convert the decimals to have the same denominator.
Find the least common multiple of both fractions' denominators:
Multiples of 8: {8,16,24,32,40}
Multiples of 10: {10,20,30,40}
The least common multiple of 8 and 10 is 40.
Multiply the fractions by a number that will make their denominator 40:


Now you can add these fractions together:

Simplify this fraction:

The answer should be
1/8.
