An engineer is designing a storage compartment in a spacecraft. the compartment must be 2 meters longer than it is wide, and its depth must be 1 meter less than its width. the volume of the compartment must be 8 cubic meters.
a. write an equation to model the volume of the compartment.
b. list all possible rational roots.
c. use synthetic division to find the roots of the polynomial equation. are the roots all rational numbers?
d. what are the dimensions of the storage compartment?
i really only need a. and d. though, .

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.

Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x^2 - 8 = -6x a. –7.12, 1.12 b. 7.12, –1.12 c. 7.12, 1.12 d. –7.12, –1.12
