Answer:

Step-by-step explanation:
It is already in its simplest form. When you simplify a square root, you break the number down into prime numbers.
For example,
can be changed into
. Since 2 is in there twice, you'd take it out and make
.
13 is already a prime number, so you cannot simplify it further.
Their distance differs by 15 miles for each hour of travel time. Thus, the travel time of interest is
.. (180 -144) miles/(15 miles/hour) = 2.4 hour
The red car's speed is 180 mi/(2.4 h) = 75 mi/h.
The blue car's speed is 144 mi/(2.4 h) = 60 mi/h.
Given:
Length of cloth = 9 yards
Length of pieces =
yards each
To find:
The number of pieces of cloths after cutting.
Solution:
Let n be the number of required pieces.
Length of each piece is
yards. So, the length of n pieces is
yards.
The length of the whole cloth is 9 yards. So,
yards must be equal to 9 yards.

Multiply both sides by 3.


Therefore, the Greata have 27 pieces of cloths.
