Answer:
2. 5 + 12
3. 35
4. (3x4) - 3(9)
5. number inside parenthesis should be -50, hence the equation will yield 0
Step-by-step explanation:
2. Changing the order of addends does not change the sum
3. The sum of 0 plus any number is that number.
4. Multiply each addend (numbers inside the parenthesis) individually to the number outside parenthesis.
5. The additive inverse of a number is its opposite number leading to a zero sum of both numbers.
Answer:
a(5-3) = 5a - 3a
(8x)y = 8(xy)
(-9) + 3 = 3 + (-9)
12(1) = 12
17 + (-17) = 0
