Answer:
-51 (no options are matching)
Step-by-step explanation:
Given: (–2)2 + (–42) + (18 – 23).
we know, 2*2 = 4, and in integer multiplication if any negative integer is multiplied with positive integer, then the result will have a negative sign.
= -4 + (-42) + (18 – 23)
Here, we have open the brackets, and written the respective signs with the integers,
= - 4 - 42 - 5
now, we will perform the integer addition. Adding all the positives together & he negative numbers together
= -51
PS: It happens to be that none of the given options match with the correct answer. But, i have solved taking the expression, i hope it helps
