Answer:

$b^6z^612a^5$

Step-by-step explanation:

The first step is to combine like terms, and multiply them together first. Since multiplication is commutative, it doesn't matter in what order you do it. Therefore, this can be rewritten as $(2a^2\cdot 6a^3)\cdot(b^4\cdot b^2)\cdot(z\cdot z^5)=(12a^5)\cdot(b^6)\cdot(z^6)=b^6z^612a^5$ . Hope this helps!

Rob is saving to buy a new MP3 player. For every $14 he earns babysitting, he saves $5. On Saturday, Rob earned $84 babysitting.

Bond [772]

He saved 30 dollars through babysitting. My math is:

84 / 14 = 6

6 x 5 = 30

I hope this helps!

Two buses leave a corner at the same time. One bus goes uptown at a constant rate of 25 mph, the other downtown at a rate of 15

vlada-n [284]

The rate of separation = 25 + 15 = 40 mph

speed = distance / time

40 = 30 / t

t = 30/40 hour = 45 minutes

Its C.
