10 days → 8 days → 9 days = 27 days

Path B:

B1 → B2 → B3

2 days → 7 days → 3 days = 12 days

Path C:

C1 → C2 → C3

10 days → 8 days → 12 days = 30 days

Then the duration of the critical path is 30 days, we can't conclude the project until each path has finished

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
