A submarine starts at 0 units and has groups of 3 floats and groups of 4 anchors attached. Using these groups of floats and anchors, write as many different expressions as you can that would make the submarine's final position -5 units.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

noncoplanar points are points that do not lie on the same line.

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours
