Mr. Gardner can get a 24-pack of chocolate bars for $6.80. How much would he have to pay for a 12-pack of chocolate bars if the ratios are proportional?

How to choose the sign of the radical in the denominator of the formula for the distance from a point to a line.

Amodel rocket is launched from a roof into a large field. the path of the rocket can be modeled by the equation y = -0.04x^2 + 8.6x + 4.8, where x is the horizontal distance, in meters, from the starting point on the roof and y is the height, in meters, of the rocket above the ground. how far horizontally from its starting point will the rocket land? a. 0.56 m b. 215.56 m c. 431.11 m d. 215.74 m

Solve this 364x-64x=300x and 12(x2–x–1)+13(x2–x–1)=25(x2–x–1)
