Okay I don't know much you need explained so I'm gonna explain pretty much everything. Starting off, you need to follow the PEMDAS rules. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. So when solving you have to do it in this order.
A-(5)(0.6)*7=21
B-(4/5)(15)+8=(0.8)(15)+8=20
C-4(8+2)/2=4(10)/2=40/2=20
D-14+4(2+3)=14+4(5)=14+20=34
If you need any clarification just lmk :)
