All but B, as on B an a can be factored out
A is the correct answer
Or
Vertex = (-5,-4), y-intercept = (0,21), x-intercepts = (-7,0) and (-3,0), axis of
symmetry is x = -5
<u>Answer:</u>
The correct answer option is 'Every tenth student in the main hallway between class.'
<u>Step-by-step explanation:</u>
Every tenth student in the main hallway between class would best represent the sample population since majority of the students transit this hallway unlike the rest of the options.
For instance, polling every tenth student in the library at lunch would result in the favor of views of students who frequently visit the library and polling every tenth student in the student section at the school football game would go in favor of those who prefer sports.
percent discount = (discount)/ original * 100
= (20)/250 * 100
=.08*100
= 8 percent
He got an 8 percent discount
Answer:
g=3
Step-by-step explanation:
f(g) = g^2 +3g
Let f(g) = 18
18 = g^2 +3g
Subtract 18 from each side
18-18 =g^2 +3g-18
0 = g^2 +3g-18
Factor
0 = (g+6) (g-3)
Using the zero product property
g+6 =0 g-3 =0
g = -6 g =3
The only solution listed is g=3
