Answer:
B and D
Step-by-step explanation:
F ( x ) = x² + 8 x - 6 = x² + 8 x + 16 - 16 - 6 =
= ( x + 4 )² - 22
Coordinates of the vertex : ( - 4, - 22 )
x-2=7
apply additon property of equality
x-2+2=7+2
x=9
Answer:

Step-by-step explanation:
step 1
Find the volume of the tank

step 2
we know that
If the tank is 1/3 full of water
then
the volume of water required to completely fill the tank is equal to 2/3 of the tank capacity
so

Paula 34%. 21 divided by 60
Cory 35%. 16 divided by 40
Krista 40%. 17 divided by 50
