First, find the area of the circle.
A=(pi)*r^2
A=3.14*10^2
A=3.14*100
A=314
Next, find the area of the square
A=l*w
A=20*20
A=400
Finally, subtract the area of the circle from the area of the square
400 - 314 = 86
No, this is not the correct translation of "twice a number x, plus 8." The correct translation would be 2x + 8.
That translation you wrote would be for 2 times 8 more than number x or something like that.
Use long division to find the quotient below (x²+15x+56)÷(x+8) = x + 7
