First you need to find how many inches is in 6.2 feet which is 74. Then you need to multiply that by 2.54 to get the amount of centimeters. Which is 182.88. So the answer is 182.88
What you must do in this case is to find the roots of the polynomial. We have then: x ^ 2 + 20x + 100 = 36 Rewriting: x ^ 2 + 20x + 64 = 0 The values of the roots are: x1 = -4 x2 = -16 Remember that the values of the roots are what make the polinome zero Answer: x1 = -4 x2 = -16
