This is
as a fraction
X^1/2 - x
-2x^3 - x^1/2 - x
-2x^3 - 2x
i think this is it
i am not sure but it think its 6 root 2
Answer:
10a + 2b
Step-by-step explanation:
Add the lengths of all sides:
3a + b + b + 2a - b + 3a + b + b + 2a - b
Now combine like terms:
10a + 2b
Step-by-step explanation:
find the area as if it was a rectangle so do 14x12 then subtract the area of half a circle with a diamater of 12
