Step-by-step explanation:

the question says that k is an expression where x is a variable soo...

rewrite the given expressio with bases of 3

27×9^3x = 3k

3^3 × 3^2(3x) = 3k

Rule of exponent says that equal when you multiple you add exponent. Another rule says that equal bases cancel

3^6x+3 =3^k

IS this corretct ? THANKYOU! :D WILL REWARD BRAINLIEST ANSWER!
AlladinOne [14]
No, the answers are incorrect.
When reflected over the y-axis, if the x is positive, then it becomes negative, but if the x is negative, then it becomes positive. Also, the y will not change.
The answer should be 
X prime: (0,-6)
Y prime: (10,4)
Z prime: (-3,-1)

A car travels 350 miles on 20 gallons of gas how many gallons will be used to travel 875 miles
tino4ka555 [31]

Hi there! You will need to do a unit rate, so you would do 20/ 350 which is a weird number 0.05714285714 , and then you multiply 0.057142857148 * 875= 50 gallons. So for 875 miles you will need 50 gallons of gas.

A wooden board has a volume of 0.225 cubic m and a mass of 146.25 kilograms.
Triss [41]

Answer:

650 kg/m³

Step-by-step explanation:

The density is the ratio of mass to volume. The volume is the product of the dimensions of the prism.

 density = (146.25 kg)/((1.5 m)(0.75 m)(0.2 m)) = 146.25/0.225 kg/m³

 = 650 kg/m³

Hope this answer helps you :)

Have a great day

Which statements are true about the multiplication and division properties of rational expressions? Check all that apply. The cl
natka813 [3]

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.
