Step-by-step explanation:
A.Is correct since 40 plus 8.032 is 48.031 (Check Your selves)
B.Is correct since 48 ones = 48 and 31 thousandths =0.31
C.Is Wrong since 48(Well is correct )plus 0.31 not 0.031,not 31 thousandths.
D.Correct since 40 plus 8=48 and 0.03+0.0001 is 0.031.

Answer:
The center is at (-3, -2) and the radius = 1.
Step-by-step explanation:
We can do this by converting the given equation to standard form.
x^2+6x+y^2+4y+12=0
x^2+6x+y^2+4y = -12
Completing the square on the x and y terms:
(x + 3)^2 - 9 + (y + 2)^2 - 4 = -12
(x + 3)^2 + ( y + 2)^2 = -12 + 9 + 4
(x + 3)^2 + ( y + 2)^2 = 1
So the center is (-3, -2) and the radius = 1.
No.
Since w = 8, you must replace the variable with the number associated to it.
So, it would be 5 + 8 = 58
5 + 8 is not equal to 58, it is equal to 13.
If you wanted to find out what w was, simply subtract 5 on both sides.
w = 58 - 5
