Step-by-step explanation:
here,
x^2 -3xy-18xy^2
=x^2-(6-3)xy-18xy^2
=x^2-6xy+3xy-18y^2
=x(x-6y)+3y(x-6y)
=(x-6y)(x-3y)
Answer:
See below.
Step-by-step explanation:
4(18-3k)=9(k+1)
72-12k=9k+9
+12k +12k
72=21k+9
-9 -9
63=21k
/21 /21
3=k

Answer:
that's my question too ☹️
Answer:
9 and 3
Step-by-step explanation:
Let the first number be x and second number be y hence their sum
x+y=12 ......(1)
Making x the subject theb x=12-y
Three times be first number is 3x
3x-y=24.......(2)
Adding the two sets of equations then
4x=36
X=36/4=9
The second number will be 12-9=3
So the first number is 9 and second is 3
