Answer:
3
Step-by-step explanation:
Each of the lines lengths multiply by 3.
P=5 because the parenthesis mean multiplication, and when you multiply 3 times 5, you receive a product of 15. Then, 15-4 is 11, meaning that p=5.
There has to be something in between the two numbers, for example 7 x 7 or 7+7 not just 7 7. Without the equation it would be highly impossible to answer :D
