Answer:
63 m
Step-by-step explanation:
Perimeter is 276, 2L + 2W = 276, so L + W = 138
L = 75
138 - 75 = W
63 m
It should be 13 since 13+8 = 21. 21-7 = 13
The composite is 4 .

Add the three numbers together, then divide by 3 because there are 3 numbers.
66+62+82= 210 = 70
70 is the average of these 3 numbers.
Hope this helps! :)
It has complex roots so we can just say it is non factorable. The sum of the roots is -3 and the product is 10.<span />
