A square has two lengths, (6x-1)cm and (4x+6)cm. What is the length of one side of the square, the answer must be written in the form, side=cm

9514 1404 393

  side = 20 cm

Step-by-step explanation:

We assume the two given lengths are sides of the square, so are equal to each other.

  6x -1 = 4x +6

  2x = 7

We could find x = 3.5, but we can use 2x, too.

  (2)(2x) +6 = 2(7) +6 . . . find the side length

  4x+6 = 20 . . . . the side length of the square

__

  side = 20 cm

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

14
