Answer:
The correct options are:
- The closure property of multiplication states that the product of two rational expressions is a rational expression.
- The commutative property only holds true for the multiplication of rational expressions.
- The properties of rational expression multiplication and division are parallel to the properties of rational number multiplication and division.
Step-by-step explanation:
We know that if a and b are two rational expression than :
Closure property of multiplication states that:
a.b is also an rational expression.
Commutative property under multiplication is given by:
a.b=b.a
The commutative property holds only under multiplication and not division since, if a=0 then,
a/b=0
but b/a is not defined.
Also, the property of rational expression are parallel to the properties of rational number.
Answer:
The actual mass is either 453 or 447
Step-by-step explanation:
7 percent of 450
= (7/100) * 45
= 3.15
error = 3.15 g
hence actual mass
= 450 + 3.15
= 453.15
or
= 450 - 3.15
= 446.85
