Answer:

Step-by-step explanation:
The given function is
.
When we compare to
, we have
and c=10
The equation of the axis of symmetry of a vertical parabola is:

Also from the question the axis of symmetry is x=6
We substitute the values to get:




C.) 30 since they both have 5's just take them out then subtract 50 and 20 *but make sure u take out the decimal though* so after u subtract u will get 30 then line it up and put the decimal back then it will be .30
Answer:

Step-by-step explanation:
Simplify the radical by breaking the radicand up into a product of known factors.
Like this :
<7 and <10 are each 84 degrees
4(4) -4 = 16-4 = 12
She was wrong because she thought that x= 6
