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:
A triangle where all three sides are different in length. Try this Drag the ... They are unusual in that the are defined by what they are not.
I can’t see so sry try a different angle
32 = 2x2x2x2x2
99 = 11x3x3
100 = 5x5x2x2
400 = 2x2x2x2x5x5
39 = 3x13
35 = 5x7
80 = 2x2x2x2x5
42 = 2x3x7
5 = 1x5
78 = 2x3x13
A. 23°
because 85°-62°=23°
*Hope this helped! :)
