To Find the least common denominator you have to find the multiples of each number
multiple means the product of each factor
so the multiples of 4 would be 4 8 12 16 20
you want to name at least five multiples but if there are not the same multiples you might have to list more
the multiples of 5 would be 5 10 15 20
then I can stop there because I have found two of the same multiples
so now we have our least common denominator which is 20
HOPE THIS HELPS!!!
Mhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
It is a right triangle so,
a² + b² = x²
9² + 12² = x²
225 = x²
√225 = x
15 = x
Hope this helps :)
Answer:
100000000
Step-by-step explanation:
Basic way to do this when using 10's 100's 1000's and up, count the number of zeros on the end and multiple the first regular number then add the zeros back :D
The formula for perimeter (total length all around sides) for a rectangle is
P(L,w) = 2(L+w)
Assuming the neighbour wants to fence all around each yard, the total fence length is the total of two perimeters, namely
Length of fence
= 2(65+45) + 2(35+45)
=2(110)+2(80)
=220+160
=380 feet.
