Answer:
Step-by-step explanation:
4(x-3)2-5 = 139
(4x-12)-5=139
-20x + 60 = 139
-20x +60 - (60) = 139- 60
-20x = 79 divide both sides by -20
x = -3.95
Let x be the no of boxes.
120x = 14501
x = 14501/120
Upon division the quotient +1 = The no of boxes required and
The remainder is the amount of popcorn in the last box
No of boxes = 121 boxes
Kernels in the last box = 101 kernels
Answer: 2 real zeros
discriminant: b^2 - 4ac
a = 3, b = -7, and c = 4
so, (-7)^2 - 4(3)(4) = 1
Since the discriminant is positive, there are 2 real zeros, if the discriminant was negative there would be 2 complex zeros, and if the discriminant equaled 0 then there is one real answer
I am sorry there is not enough information to work with plus the question doesn't even make sense.
