Answer: -15yx^2
Step-by-step explanation:
-12x^2 * y -3x^2 * y=
-12(x^2 * y)-3(x^2 * y)=
(-12-3)(x^2 * y)=
-15x^2 * y=-15yx^2
I am pretty sure your answer is going to be 243
I hope this helps, and good luck!!
Answer:
2x + 3y > 100

Solve for :
subtract 
from both sides:
divide both sides by 
:
Solve for :
subtract
