Answer:
a
Step-by-step explanation:
If patio is square it means that area of if is

where a is one side
Now we can substitute A=200 and solve eq

a=

a=14.1421
Now we are rounding to the nearest tenths
a=14.1 because next number is 4 and is less then 5.
The result is 14.1
X + 2/3 = -2(4/5x-7)
Is equivalent to -2(x+2/3)=4/5x-7
So the answer would be A
Combine the like terms.
4x^4+3x^3-16x^2+27x-18
I think your answer might be C i am not sure but i am thinking it is
