Not if you keep the ' l ' before the ' XX ' where it belongs. If it's before, then it means take the ' l ' away from them, and you get 19 just as you should.
Now I understand this crazy question that keeps coming around.
Answer:
Step-by-step explanation:
To find the inverse of a function, you want to replace x with y and y with x. Then, you solve for y.
[replace y with x and x with y]
[subtract both sides by 7/2]
[multiply both sides by -2/3]
[distribute]
Now, we have our inverse function.
Your answer would be 12.
She can use 12 connecting cubes to make the model in only two ways.
