Multiply the 49 by 2

Add

The answer is

Hope this helps!
Answer:
Concept: Mathematics
When you multiply a number by something to the 10 power of something then you move whatever place of the exponential to the right if its positive and left if it's negative.
- 1.365 × 10^1
- You see its positive 1 hence we move one space to the right
- Our answer is now 13.65
You keep doing the same thing
- 1.365 × 10^2
- 136.5
Lastly
- 1.365 ×10^3
- 1365
Rate positively and give 5 stars
That would be 20 x 19 x 18 which equals 6840.
After first place is chosen, 19 spots left and so on.
The answer is 6840 ways.
im quite positive that the x-intercept is 1,6
