Both are right b/c like sean says you can add zero and itll still be -100 but candice is also right b/c because you can add any # to that -100 but you can also add a negative # to get it back to -100. for example: -100+23= -77 but if you also add a negative 23 it would be right back to -100.
Answer:
17 is C
18 is add
19 is C
Step-by-step explanation:
Question 18 is worded a little weird.
so. (x^2)(x^3) = x^5, so you should add the expotents when you are multiplying them.
3a-72yd 3b-72ft
4a-(left and right 30ft)(up and down 12 ft)
4b-(left and right 25 yds)(up and down 15 yds)
I really hope this helps!! :)
R=-8 because you take 8 and subtract 16 from it.
