The product is: 25x^2-5xy-6y^2
1. get rid of your parenthesis
2. in order to do so you must look inside of the parenthesis and check if you have any like terms if so combine them
3. next use the distribution property or otherwise known as the rainbow
4. if you have an exponent to the right of your parenthesis then use the exponent rule
5. combine like terms by adding coefficients
6. finally combine the constants

8 employees exercise at least three times a week
<em><u>Solution:</u></em>
At the office where Mika works 41% of the 19 employees exercise at least three times a week
To find: Number of people who exercise at least three times a week
From given information,
Total employees = 19
Employees exercise at least three times a week = 41 % of total employees
Therefore, we have to evaluate 41 % of 19
Number of people exercise at least three times week = 41 % of 19
![\rightarrow 41 \% \text{ of } 19 = 41 \% \times 19\\\\\rightarrow 41 \% \times 19 = \frac{41}{100} \times 19 = 0.41 \times 19\\\\\rightarrow 41 \% \times 19 = 0.41 \times 19 = 7.79 \approx 8](https://tex.z-dn.net/?f=%5Crightarrow%2041%20%5C%25%20%5Ctext%7B%20of%20%7D%2019%20%3D%2041%20%5C%25%20%5Ctimes%2019%5C%5C%5C%5C%5Crightarrow%2041%20%5C%25%20%5Ctimes%2019%20%3D%20%5Cfrac%7B41%7D%7B100%7D%20%5Ctimes%2019%20%3D%200.41%20%5Ctimes%2019%5C%5C%5C%5C%5Crightarrow%2041%20%5C%25%20%5Ctimes%2019%20%3D%200.41%20%5Ctimes%2019%20%3D%207.79%20%5Capprox%208)
Thus approximately 8 employees exercise at least three times a week
