For the zero product property questions it's choices 2 and 3 since they're quadratics factored and set equal to zero.
for the quadratic formula questions it would be answer choices 2 and 3 also because they're unfactored trinomial quadratic expressions

3.5 x 8 = 28
Step-by-step explanation:
Feeding the whole school (8/8) would take 8 times as long as feeding 1/8 of the school.
3 1/2 can become 3.5 if that's easier for you to work with.
Feeding 1/8 of the school is 3.5 x 1 = 3.5
Feeding 2/8 of the school is 3.5 x 2 = 7
Feeding 8/8 of the school is 3.5 x 8 = 28
It takes 28 minutes to feed the whole school (8/8)
Answer:
Interquartile Range = 34
Range = 55
Step-by-step explanation:

Quartile 3 - Quartile 1 = IQR
68 - 34 = 34
