X²+14x+49+17=-96+49
(x+7)²=-64, x+7=±8i, x=-7±8i, so x=-7+8i or -7-8i.
7 + 14x means that a number x (x could be any real number) times 14 is added to 7.
So if x = 2:
7 + 14x = 7 + 14(2) = 28 + 7 = 35
Happy to help!
The answer would be 10 it is cheaper you must divide here is my work
<span>You divide unit per price = 10/$6.75 = $1.48
12/$7.25 = $1.65
Which means 10 units are cheaper</span>
