Answer:
a) 72
Step-by-step explanation:
The rightmost digit, 5, is in the ones place, so its value is 5.
The next digit to the left, the 4 is in the sixes place, so its value is 4 * 6 = 24.
The next digit to the left, the 2, is in the 36 place, so its value is 2 * 36 = 72.
Answer: a) 72
The pythagorean theorem states: a² + b² = c²
Where c is the longest side (hypotenuse).
So we plug in and solve for the third side "b".
a = 12, c = 13, so:
12² + b² = 13²
144 + b² = 169
b² = 169 - 144
b² = 25
b = 5
We can double check the pythagorean theorem to make sure:
12² + 5² = 13²
144 + 25 = 169
So the unknown side is definitely 5.

Identity property of 0 for addition means a number plus 0 will still be that same number. So -756 + 0 is still -756
