Suppose a line that appears parallel to side BC¯¯¯¯¯¯¯¯ of △ABC intersects sides AB¯¯¯¯¯¯¯¯ and AC¯¯¯¯¯¯¯¯ at points X and Y respectively, and AX/AB=1/2. How can you determine if the line is or is not parallel to BC¯¯¯¯¯¯¯¯? Explain.

Part a : solve -vp + 40 < 65 for v part b : solve 7w - 3r = 15 for r show your work .

Look at arnold's attempt to solve the equation for b: 3b = 12 b = 3 · 12 b = 36 describe the mistake that arnold made.

Prism m and pyramid n have the same base area and the same height. cylinder p and prism q have the same height and the same base perimeter. cone z has the same base area as cylinder y, but its height is three times the height of cylinder y. the figures and have the same volume.
