Answer:
Well the answer is 57.
Step-by-step explanation:
Okay think about it 10+10 is 20 how do you know this well 1+1=2 and add a zero. So in 10+47 4+1=5 and keep the 7 because the other number is a zero which has no affect on the number unless both numbers are zero.
The answer is A..... 2 2/3
The third side measures exactly 15 centimetres (cm).
The negative before parenthesis gonna multiply to the number in the parenthesis so we will have : -282-1017 so we can add them together and we gonna have :
-282-1017 = - 1299 :))) thats the answer
