Below are the steps Jafar used to solve for the value of x. How would you respond to Jafar? Include in your response whether or not Jafar made a mistake, what the mistake is, why this step will not work and then model the correct solution process for Jafar.
Step 1: 2x2 - 4x = 16
Step 2: x22x=8
Step 3: x2= 2x+8
Step 4: x{1x = (2x+8) IX
Step 5: x=2 + 8
Step 6: x=10

(x-5)1/2+5=2 what is a possible solution?

For every corresponding pair of cross sections, the area of the cross section of a sphere with radius r is equal to the area of the cross section of a cylinder with radius and height 2r minus the volume of two cones, each with a radius and height of r. a cross section of the sphere is and a cross section of the cylinder minus the cones, taken parallel to the base of cylinder, is the volume of the cylinder with radius r and height 2r is and the volume of each cone with radius r and height r is 1/3 pie r^3. so the volume of the cylinder minus the two cones is therefore, the volume of the cylinder is 4/3pie r^3 by cavalieri's principle. (fill in options are: r/2- r- 2r- an annulus- a circle -1/3pier^3- 2/3pier^3- 4/3pier^3- 5/3pier^3- 2pier^3- 4pier^3)
