Hey there!
1. To solve 9 x 5 , I could add the number 9 five times . . .
9 + 9 + 9 + 9 + 9 = 45
9 x 5 = 45 <----
2. I would use the same strategy as the first one, except add the number 8 five times . . .
8 + 8 + 8 + 8 + 8 = 40
8 x 5 = 40 <----
Hope this helps you.
Have a great day!
Answer:

Step-by-step explanation:
The 3 roots are given out of which 2 are real and 1 is imaginary. For a polynomial of least degree having real coefficients, it must have a complex conjugate root as the 4th root. Therefore, based on 4 roots, the least degree of polynomial will be 4. Finding the polynomial having leading coefficient=1 and solving it based on multiplication of 2 quadratic polynomials, we get:

- We have a bag with 4 white chips and 6 black chips
- Question : What is the probability of randomly choosing a white chip, not replacing it, and then randomly choosing another white chip?
4 white and 6 black
4 + 6 = 10
Choosing the first white chip : 
Since we took one out , now
3 white chips , 6 black chips
3 + 6 = 9
Choosing another white chip :
