The work of a student to find the dimensions of a rectangle of area 8 + 12x and width 4 is shown below: step 1: 8 + 12x step 2: 4(4) + 4(8x) step 3: 4(4 + 8x) step 4: dimensions of the rectangle are 4 and 4 + 8x in which step did the student first make an error and what is the correct step? (1 point) step 2; 4(2) + 4x(2) step 2; 4(2) + 4(3x) step 3; 4 + (4 + 8x) step 3; 4 + (4 ⋅ 8x)

Astudent found the solution below for the given inequality. |x-9|< -4 x-9> 4 and x-9< -4 x> 13 and x< 5 which of the following explains whether the student is correct? -the student is completely correct because the student correctly wrote and solved the compound inequality. -the student is partially correct because only one part of the compound inequality is written correctly. -the student is partially correct because the student should have written the statements using “or” instead of “and.” -the student is completely incorrect because there is no solution to this inequality.
