Which statements are true about the multiplication and division properties of rational expressions? check all that apply. 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 associative property holds true for both the multiplication and division of rational expressions. the associative property states that the way in which two or more factors are grouped in a product changes the value of the product. the properties of rational expression multiplication and division are parallel to the properties of rational number multiplication and division.

The correct options are:

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.

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
