Answer:
B.
Step-by-step explanation:
Parentheses mean multiplication in this case. So it would be 2 x -3 OR -3 + -3. When multiplying a negative and a positive the answer will ALWAYS be negative. So you would move to the left on a number line.
4/5+3/5 = 7/5 = 1.4
3.5X5 = 17.5
1.4 + 17.5 = 18.9 = 18 9/10
The answer is (4x20) + (4x4) which equals 96
