Whenever a number is beside a parenthesis without a sign it means multiplication. So you would use PEMDAS work in parenthesis then exponents, multiplication (from left to right) addition and subtraction (from left to right). so you would add 20+3 and get 23 then multiply that by -5 to get -115 as your answer.

All you have to do solve
Step-by-step explanation:
Replace the x with whatever number is in the f(number)
The shape has 9 sides.
Sum of interior angles = (n-2) x 180, where n is the number of sides.
Sum of interior angles = (9-2) x 180 = 7 x 180 = 1,260 degrees.
