Answer:
B
Step-by-step explanation:
Answer:
The additive inverse of −5 is +5, so 18 − (−5) = 23. The additive inverse of −5 is −5, so 18 − (−5) = 23. The additive inverse of −5 is −5, so 18 − (−5) = 13.
Use "PEMDAS" (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction) to know what to do first.
(15 + 6)^{2} - (8 - 5)^{2} Solve the insides of the parentheses
21^{2} - 3^{2} Solve the exponents (21 x 21) and (3 x 3)
441 - 9 Subtract
432
