Find the greatest common factor of 15 x²y³ and -18 x³yz .

3 x² y¹

Step-by-step explanation:

15 x²y³ =3. 5. x². y³

-18x³yz = -2. 3².x³. y¹. z¹

so, the GCF = 3. x². y¹

Solution given:

15x²y³=3*5*x*x*y*y*y

-18x³yz=-3*2*3*x*x*x*y*z

over here common is

3*x*x*y

so

greatest common factor is 3x²y¹

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches
