I need help with both questions please!

Use sigma notation to write the following Riemann sum. Then, evaluate the Riemann sum using formulas for the sums of powers of positive integers or a calculator. The right Riemann sum for f(x) = x + 10 on [0,6] with n = 50 Write the right Riemann sum. Choose the correct answer below. 3 O A. 3 I MS 25 k + 10 25 O B. K, 25K + 25 50 Oc. E 25k 192 OD. 2 25 k - 10 The right Riemann sum is (Round to two decimal places as needed.) Click to select your answer(s)
