Answer:
Step-by-step explanation:
- √(14 - 2√13) * √(14 + 2√13) =
- √(14 - 2√13)(14 + 2√13) =
- √(14² - (2√13)²) =
- √(196 - 4(13)) =
- √(196 - 52) =
- √144 =
- 12
Answer:
-20 points for a incorrect answer
Step-by-step explanation:
-160/8=20
Answer:
4.2 is: 1.) between 4 and 5 closer to 4
7/8 is: 3.) between 0 and 1 closer to 1

Let A = 4 A=4 A=4 cm and B = 9 c m B=9
cm B=9cm. The distance between A A A
and B B B is the absolute value of their
difference: IA-BI=B-Al=14-9..
Make a proportion 20 miles/4 hours= 75miles/x. cross multiply gives you 20x=300. this will give you x = 15 hours
