It equals 45 degrees because if you have a ~ line it means you have 45 degrees and don't forget to thank me
Answer:
65
Step-by-step explanation:
let's place 9 in place of p and 4 in place of q. I will use a star in place of that symbol for the sake of my convenience having to look for it, apologies.

8x - 4 is an expression. This means that x can mean anything.
If you mean 8*-4, the answer would be -32 because 8 multiplied by 4 is 32, but since a positive multiplied by a negative equals a negative, the product would become a negative.
