Answer:
D 7x( x^2y) ^1/3
Step-by-step explanation:
5x (x^2y)^1/3 +2 (x^5y)^1/3
We can simplify the second term
2 (x^5y)^1/3 = 2 (x^3 * x^2y) ^1/3
We know that (a*b) ^c = a^c * b^c
2 (x^3 * x^2y) ^1/3 = 2 (x^3 )^1/3*( x^2y) ^1/3
2*x*( x^2y) ^1/3
Replacing this into the original equation
5x (x^2y)^1/3 +2x( x^2y) ^1/3
The term inside the cube root is the same, so we can add the terms on the outside
(5x+2x) 2x( x^2y) ^1/3
(7x)( x^2y) ^1/3
Answer:
Cake B
Step-by-step explanation:
If you pick Cake A, you'd get the following:
= ~ 28 square inches for you
With Cake B:
square inches for you
Ok, here's a trick: If you're converting a smaller unit to a bigger unit in metric system, you divide by 10. When you are trying to convert a bigger unit to a smaller unit, multiply by 10. Decimeters are 1/10 of a meter, so you are going to multiply 2 by 10 because you are converting a bigger unit to a smaller unit, in which you get 20.
So your answer is 20 decimeters.
Answer:
d
Step-by-step explanation:
rearrange it like an equation.
take everything else out of the middle apart from x.
make sure that what you do to the middle you do to both sides
Multiply the equation:
The solution set is the same, because multiplying both sides of an equation by a non-zero number doesn't change the solution set. In fact, if you rewrite the equation as
Multiplying this by 3 (or whatever number, for all it matters) gives
Now, a product is zero if and only if at least one of the factor is zero. So, either 
or
Since the first is clearly impossible, the second one must be true, which is the original equation.
