Please write the answer like you would put in the boxes

Problem 7-07 (Algorithmic) The following questions refer to a capital budgeting problem with six projects represented by 0-1 variables x 1, X2, X3, X 4, X 5, and x 6 a. Write a constraint modeling a situation in which two of the projects 2, 3, 4 and the constant is "1" it must be entered in the box. must be undertaken. For those boxes in which you must enter subtractive or negative numbers use a minus sign. (Example: -300) If your answer is zero enter "0". If X2 + X3 + X4 + X6 = b. Write a constraint modeling a situation in which, if projects 3 and 6 must be undertaken, they must be undertaken simultaneously. For those boxes in which you must enter subtractive or negative numbers use a minus sign. (Example: -300) If your answer is zero enter "0". If the constant is "1" it must be entered in the box. X3 + X6 c. Write a constraint modeling a situation in which project 2 or 5 must be undertaken, but not both. For those boxes in which you must enter subtractive or negative numbers use a minus sign. (Example: -300) If your answer is zero enter "0". If the constant is "1" it must be entered in the box. X2 + X5 d. Write constraints modeling a situation where project 5 cannot be undertaken unless projects 2 and 3 also are undertaken. For those boxes in which you must enter subtractive or negative numbers use a minus sign. (Example: -300) If your answer is zero enter "O". If the constant is "1" it must be entered in the box. X5 X2 e. In addition to the requirement in part (d), assume that when projects 2 and 3 are undertaken, project 5 also must be undertaken. For those boxes in which you must enter subtractive or negative numbers use a minus sign. (Example: -300) If your answer is zero enter "0". If the constant is "1" it must be entered in the box.
