Answer:
odd
Step-by-step explanation:
If 'a' and 'b' have different parity, the result has odd parity.
__
<u>Assume a=odd, b=even</u>
(5·odd -3·even) = odd
(odd^2 +5·even) = odd
(odd)(odd) +2 = odd
__
<u>Assume a=even, b=odd</u>
(5·even -3·odd) = odd
(even^2 +5(odd)) - odd
(odd)(odd) +2 = odd
_____
The attached verifies this with numbers.
shelly sews a blanket that has an area of 170 square feet. it has 30 square blocks each the same size
30 square blocks of same size. We need to find the area of each square block. so we divide 30 from the total are 170
The area of each square = 5.66667 square feet
We know area of square = side ^2
side ^2 = 5.66667
To find side , take square root on both sides
The side of the square of each block = 2 feet
