Answer:
x = 
Step-by-step explanation:
Since l bisects PQ at M then M is the midpoint of PQ, hence
PM = MQ, that is
5x - 7 = 11 - 2x ( add 2x to both sides )
7x - 7 = 11 ( add 7 to both sides )
7x = 18 ( divide both sides by 7 )
x =

Step-by-step explanation:
the 3 consecutive even integers are x , x + 2 and x + 4 , then their sum is
x + x + 2 + x + 4 = 72 , that is
3x + 6 = 72 ( subtract 6 from both sides )
3x = 66 ( divide both sides by 3 )
x = 22
x + 2 = 22 + 2 = 24
x + 4 = 22 + 4 = 26
the 3 consecutive even integers are 22, 24 , 26
The square root of -1 is i. So you can simplify it to 7(sqrt)-1, which becomes 7i.
