We are asked to evaluate Marlena's solution in solving the expression below: 2x+5 = -10 -x The first step is to re-write the expression and transpose same terms in the left side while all numbers are transferred to the right side such as shown below: Step 0: 2x+5 = -10 -x Step 1: 2x + x = -10 -5 Step 2: 3x = -15 Step 3: x =-15/3 The answer is x=-5.
1.) Find the area of the circle at the top ( A= pi x radius squared ) 2.) radius is 5.55 (half of 11.1) 3.) A= pi x 5.55 squared 4.) area of circle =96.77 5.) multiply area of circle(96.77) by height (20) 6.) answer = 1935.38
