Solving quadratic equations - factoring.

Factor to solve each problem 1-3

1) 1 1/2 ft.

2) 12 m.

3) 6 ft.

Step-by-step explanation:

1, 2) If the area is the same, then the sides are exactly half that of the surrounding square.

3) 9^2 = 81 ft^2 (or sqrt(81) = 9), if we take this 9 and subtract the 3 ft from it we will get the original side lengths.

look a the sides they are perpendicular

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
