Answer:

The greatest common factor = 4a.b^2

Step-by-step explanation:

Given: 8a^3.b^2 and 12ab^4

To find the greatest common factor, we have to find the prime factors.

8 a^3.b^3 = 2.2.2.a.a.a.b.b

12a.b^4 = 2.2.3.a.b.b.b.b

The greatest common factor = 2.2.a.b.b

The greatest common factor = 4a.b^2

Hope this will helpful.

Thank you.

Divide the square root of 81 by the difference between the product of-1 and -3 and the square root of 4

kherson [118]

Answer: $\frac{9}{1}$

Step-by-step explanation:

FIrst find the square root of 81.

$\sqrt{81} = 9$

The square root of 81 is 9.

FInd the product of -1 and -3 by multiplying the -1 by -3.

-1 * -3 = 3

next find the square root of 4.

$\sqrt{4} = 2$

Now it said divide the square root of 81 which is 9 by the difference between 3 and 2 and the difference between 3 and 2 two is 1.

Thos means that the answer will be 9/1.

-2x+8y-4 *parallel *perpendicular *neither *please help asap!*

guapka [62]

Answer:

Step-by-step explanation:

y = m x + b

Then we can read the slope right off the equation: it is the number

represented by m.

I'll help you get one into this form:

Start with -2x+8y-4

Then add 4 to both sides: -2x+8.

Then divide both sides by 4: y = 3/4 x + 6/4.

This means that the slope is 3/4.

Try the other one on your own and reduce the slope to the smallest

possible fraction.

Now, what does this mean? If the slopes are the same, it means the two

lines are parallel. If one slope is the negative reciprocal of the

other, then the two lines are perpendicular. To get the negative

reciprocal of a number, put one over the number and then make it

negative. So:

if the number is its negative reciprocal is

2 -1/2

3/10 -10/3

-3/2 2/3

So if the two lines had these respective slopes, they would be

perpendicular.

If the slopes are neither the same nor negative reciprocals, the lines

are neither parallel nor perpendicular.
