I don’t know what to do
n200080 [17]

Answer:

x = 7

y = 12

Step-by-step explanation:

To do this question you have to know your exponent rules, but also you need to know how to add fractions.

To multiply

6^(1/3) × 6^(1/4)

you can keep the 6 and just add the exponents.

That's why the answer is set up on the form 6^(x/y)

To add fractions, you need a common denominator, it is 12.

1/3 is 4/12.

1/4 is 3/12.

So 1/3 + 1/4

is the same as:

4/12 + 3/12

= 7/12

7/12 is the exponent you are looking for.

x = 7 and y = 12.

6^(1/3) × 6^(1/4)

=6^(7/12)

Answer:

12

Step-by-step explanation:

We know that AD=BC and that AB=CD. We also know the perimeter of the rectangle ABCD to be 54 units.

From this, we can add up the sides which will be equal to 54 units.

AD+BC+AB+CD=54

2x+2x+3x-3+3x-3=54

10x=60

x=6

Since we are trying to find the length of side BC we substitute this value back into 2x.

BC=2x =2*6=12

Therefore, the length of BC is 12 units.
