We want to find the axis of symmetry of the function;

STEP 1:
The equation for the axis of symmetry of a line is given as;

From the equation, a = 6 and b = -3, so,
STEP 2: Insert the values of a and b into the equation to obtain;

CONCLUSION:
Therefore, we see that the axis of symmetry is the line;
Answer:
The area is 63a
The perimeter is 39b
Step-by-step explanation:
Answer:
AC = 28 feet
Step-by-step explanation:
Point C is the midpoint of AB, so AC is half the length of AB:
AB/2 = (56 ft)/2 = 28 ft = AC
Answer:
common difference is 4
Step-by-step explanation:
12-4=8
8-4=4
