Approximating a Solution from a Table
Approximately how many hours of operation will result
in a cost of $310,000?
The table below represents the cost, in hundreds of
thousands of dollars, for operating a factory for x hours.
The data is modeled by the function
f(x) = x3-12x2+385x+57.

Can someone explain the elimination method to me for this problem?

Use the diagonals to determine whether a parallelogram with vertices u(2,−2), v(9,−2), w(9,−6), and x(2,−6) is a rectangle, rhombus, or square. give all the names that apply.

In the figure below, segment ac is congruent to segment ab: triangle abc with a segment joining vertex a to point d on side bc. side ab is congruent to side ac which statement is used to prove that angle abd is congruent to angle acd? segment ad bisects angle cab. triangle acd is similar to triangle abd. segment ad is congruent to segment ac. angle cab is congruent to angle cba.
