Answer:
Step-by-step explanation:175.42x .20=35.08 35.08Divided by 11=3.19
so each would pay 3.19 tip
total each would pay for bill would be 175.42+35.08=210.50
210.50divided by 11 =19.14
To solve this, first solve the part of the equation in parentheses: (-4+3) = -1. Then multiply using the exponent 2 squared is 2×2 which is 4. Now the equation is -4(-1)+4. Next you multiply, -4(-1)=4. You are then left with 4+4 which equals 8.
-4(-4+3)+2 squared
-4(-1)+2 squared
-4(-1)+4
4+4
8
