Answer:
What triangle. Ill fix my answer when I have it.
Step-by-step explanation:
1. Number that adds up to -12 and multiplied by the same # that gives u -13. Set it up like this because both are negative so, u need 1 negative and 1 positive.
(x-13)(x+1)
2. Same rule applies. GCF
8y(4y+1)
3. (x+3)(x-3)
The answer is A. X=-1/3 or x=2/3
To calculate the speed, divide 15.75 by 2.25 and you get 7 mph.
Ok if the number behind the decimal is 4-0... round down, But if the number is 5-9 round up.
Example:65.85
The number behind the decimal is a 8.. So round this number up to the next availible whole number, which is 66.
