Multiply and simplify the following rational expression

2x^3y^6 . 15x2
5x^2y 10x^4y

(there is 2 missing fraction lines)

Step-by-step explanation:

The expression is:

First, we will multiply the numerators together and denominators together.

This gives,

Now, we use the exponent property .

This gives,

Now, we use the exponent property

This gives,

From the properties of exponents,

So,

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
