Answer:
Step-by-step explanation:
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 area of the cross section is equal to the area of the base.
Step-by-step explanation:
12:25 is not equivalent to the rest
Distribute
a(b+c)=ab+ac so
-3(x-5)=-3x+15
-8(y+2)+-8y-16
-3(6-4b)=-18+12b
add them together
-3x+15-8y-16-18+12b
associative property
15-16-18-3x-8y+12b
add
-19-3x-8y+12b is the answer which is D
