Find the greatest common factor of -30 x^4yz^3 and 75 x^4z^2
? z^?

15x^4z^2

Step-by-step explanation:

We need to break each term into the smallest factors

30 = 3*10 = 3*2*5

75 = 3*25 = 3*5*5

-30 x^4yz^3 = -3*2*5 * yzzz

75 x^4z^2 = 5*5*3zz

What common factors are in each term

3*5**zz

15x^4z^2

18a

step-by-step explanation:

simply because it is. it's the highest common factor

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
