The commutative property of addition can be used to rarrange this to
... 0 + 18 + 34 + 26
Then the identity property of addition can be used to remove the 0 term
... 18 + 34 + 26
We can use the associative property of addition to form the sum of 34 and 26, convenient because 4 and 6 "make a 10". That sum is 60, so now the sum is
... 18 + 60
which is easily seen to be
... 78
Area=length*width
length=5+width
area=(5+w)(w)
area=5w+w^2
area=x^2+5x=300
x^2+5x-300=0
(x+20)(x-15)=0
x=15
w=15
l=5+15
l=20

2 more hours
Step-by-step explanation:
6/75 = x/100
Answer:
4 + .09
Step-by-step explanation:
Decimals are also a place value therefore in the expanded value equation, .09 in 4.09 takes its own part in the equation.
