Convert the given system to an augmented matrix. 2x1 + 2x2 − x3 = 9 −x1 − x2 = −2 3x1 + 3x2 + x3 = 1 2 2 −1 9 −1 −1 0 −2 3 3 1 1 2 2 −1 9 −1 −1 −2 0 3 3 1 1 2 2 −1 9 −1 −1 0 2 3 3 1 1 2 −1 3 2 −1 3 −1 −2 1 9 0 1 2 −1 3 2 −1 3 −1 0 1 9 −2 1 correct: your answer is correct. find all solutions by reducing the system to echelon form and back substituting. (if there are an infinite number of solutions use s1 as your parameter. if there is no solution, enter no solution.) (x1, x2, x3) = incorrect: your answer is incorrect.

which of the following statements correctly describes the expression below based on its degree and number of terms?

314 - 7x2 + 11

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
