Answer:
a=10x linear
Step-by-step explanation:
A = 10x
Length = 10
Width = x
Area = A
The formula is
A = L × W
A = 10 × x
7,-7 are the solutions
Not a perfect square so its
+-7
I would go with -7 since its the lowest amount
When you remove the 3 you subtract becuase in this case 3 is positive. subtract 3 from 3 then subtract 3 from -73.
