Just making sure my answers are right. Please show the steps clearly. Thank you so much

Step-by-step explanation:

A.

Let's split the integral into two parts, by the Sum Rule.

                             [split into 2 integrals]

                     [solve integral for each part]

                           [Remember, we need to add C for constant]

-------------------------------------------------------------------------------------------------

B.

                                   [expand into 2 integrals]

                   [simplify second integral]

                   [solve integral for each part]

-------------------------------------------------------------------------------------------------

C.

               [distribute]

                      [split into 2 integrals]

             [solve integral for each part]

                                    [solve]

-------------------------------------------------------------------------------------------------

D. *Note: I can't put -1 for the interval, but know that the 1 on the bottom is supposed to be -1.

                 [expand]

                             [split into 2 integrals]

                     [solve integral for each part]

                                     [solve]

the correct answer is 828.07
