The perimeter of a rectangular picture frame with width w inches length can be found by doing the following steps: subtract the width then the length, then add 7 inches then multiply the result by 4 a. Explain in weeds why the equation is true for this rectangle. Solve the equation in part a, for the variable c. If the picture frame's width is 8 inches, what is its length? What is its perimeter? Find all values of x that make the following two inequalities true. In each case, sketch your solution set on a number line. a. 2(x 3) 12 b. 1/3 (2x 1_ 1/2 (x 3)1 solve the equation 2(5 3x) 5(3x 7) as follows 2(5 3x) 5(3x 7) 10 6x 15x 35 10 6x 15x 15x 35 15x 10 9x 35 9x 35 10 9x 45 x 5 a. Find mistake. Explain in words what he did wrong. b. Find the correct solution.
