The radical can be further simplified because 135 is the product of 9 and 15. 9 has a perfect root of 3.
meters or 11.62 meters
Hence the name. In other words, a number is rational if we can write it as a fraction where the numerator and denominator are both integers.
D. because each day =34 and it is 5days 5×34= 170 so the answer is more than 4 gallons
Answer:
4
Step-by-step explanation:
use the Pythagoras' theorem
formula for an ABC triangle( right angled)
AB is height
BC is hypotenuse
CA is length
=
+ 
in your case
AB is 7
BC is 8
CA is unknown so we write x
=
+
64=49+
64-49=
15=
=x
3.87=x
4=x
Answer:
