Answer:

1. 4y-12

2. c

For #1 you distribute the 4 to the y and the 3. 4 times 3 equals 12.

For #2 you factor out the 3 and you get 3(5x+1)

Answer:

$\dfrac{4r^6}{st^8}$

Step-by-step explanation:

$(4r^{-2}st^4)(r^{-4}st^6)^{-2} =$

Use laws of exponents to simplify the right set of parentheses.

$= (4r^{-2}st^4)(r^{8}s^{-2}t^{-12})$

Now use the law of exponents for a product of powers with the same base.

$= 4r^6s^{-1}t^{-8}$

Finally, use the definition of a negative exponent.

$= \dfrac{4r^6}{st^8}$

What property is this? <br> (10b+12b)+7b=(12b+10b)+7b

cluponka [151]

Commutative Property

a + b = b + a

Because:

<span>(10b+12b)+7b=(12b+10b)+7b
</span>
(10b + 12b) in the first bracket is the same as (12b + 10b)
