6 cos x + 6 lim X- - It (X + 10) 2 . . . How should the given limit be evaluated? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. Use I'Hopital's Rule more than once to rewrite the limit in its final form as lim - 3 cos x X - - It O B. Use l'Hopital's Rule exactly once to rewrite the limit as lim X- - It O C. Use direct substitution. O D. Multiply the expression by a unit fraction to obtain lim () X- - ItIn (4x + 10) lim x -+ 00 In (7x + 9) +3 . . How should the given limit be evaluated? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. Exponentiale the given expression to obtain lim (). This limit can be evaluated using known limit properties. O B. 4(7x + 9) Use I'Hopital's Rule once to obtain lim X-+ 00 7(4x + 10) . Simplifying this result yields a limit that can only be evaluated by at least one more application of I'Hopital's Rule. O C. Multiply the given expression by a unit fraction to obtain lim ( ). This limit can be evaluated using known limit properties. X-+ 00 O D. Use I'Hopital's Rule once to obtain lim (). Simplifying this and then dividing each term by the greatest power of x present in the result yields a limit that can be evaluated using known X -+ 00 limit properties. O E. Use direct substitution
