The answer is a.
When you are solving problems like this you would use the equation y^2=4ax. The x and Y would be the coordinates. Based on the equation you have given the coordinates would be (6,12) and (6,-12), (24 is split up evenly between the y-axis).
Then we go on to solve the equation by plugging in the numbers 12^2=4a(6)
144=24a
144/24=24a/24
6=a
Answer:

Step-by-step explanation:

we can use the distributive property and get

and we can add like terms

and know we divide both sides by 16.5

and doing the dvision we get that

Answer:
7/2
Step-by-step explanation:
3 wholes is equal to 6 halves plus a half equals 7 halves
Answer:
x=30° y=110°
Step-by-step explanation:
80+70=150
180-150=30° 》》》》 angles in a triangle add up to 180°
x=30° opposite angles are equal
180-140=40° angles on a straight line add up to 180°
30+ 40=70
180-70=110°
y=110°
It would be D it’s really ez
