Answer:
if you rearrange to complete the square, you get (x^2-4)^2 +4
and seeing as anything squared will always be positive or zero, the lowest possible value for (x^2-4)^2 is 0, when x = 4
and 0 + 4 = 4, which is greater than 0, so positive
Step-by-step explanation:
it is c and dont get it wrong
I am so happy that I am so sorry to be so happy for now I have no never ever been in the office and I have no idea how much you have the answer is 4
<span>1/2r + 4= 3/4r - 3/2
1/2 = 2/4
3/2 = 6/4
re-write
2/4r + 4 = 3/4r - 3/4
2/4r - 3/4r = -3/4 - 4
-1/4r = -4 3/4
r = (-4 3/4) / (-1/4)
r =(-4 3/4) * (-4)
r = 76/4
r = 19</span>
