Answer: The axis of symmetry   = 1  

That's  a vertical line passing through 1 on the x-axis

Step-by-step explanation:  From standard form, ax² + bx + c

Use the values of a and b in the equation  x = -b/2a to find s, the axis of symmetry.

x = -(-6)/2(3)  

x = 6/6

x = 1

Area of the square=side²=(12 cm)²=144 cm²

Area of the circle=πr²=(3.142)(6 cm)²≈(3.142)*36 cm²≈113.112 cm²

Area of the four  sides between the square and the circle=

=Area of the square - area of the circle=144 cm²-113.112 cm²=30.888 cm²

The sum of four consecutive whole numbers is 54, what are the four numbers
anastassius [24]
Let the four consecutive numbers be x, x+1, x+2, and x+3.

The sum of the four numbers is 54, therefore
x + (x+1) + (x+2) + (x+3) = 54
4x + 6 = 54
4x = 54 - 6 = 48
x = 12

Answer:
The four numbers are 12, 13, 14, and 15

Five friends went to a local restaurant and all the buffet at $7.75 each. Two friends had dessert for $2.99 each. The following
dangina [55]

Answer:

The answer is $44.73 and what ever the explain part said on the question is not reasonable.

Step-by-step explanation:

I say this because there are 5 friends and each bill for them is $7.75 so $7.75 times 5 equal $38.75 and then the extra money for dessert is 2.99 but two times so when u add those two to $38.75 it equals $44.73.
