Answer:
28 years
Step-by-step explanation:
Sum of the years of Lance , Ted, Rosalinda = 39 + 22 +45 = 106 year
Sum of the years of Lance , Ted, Rosalinda & Erik = 33.5*4 = 134.0 year
Age of Erik = 134 - 106 = 28 years
2a^2+4a+1 is equivalent to 4a+4/2a*a^2/a+1
the two numbers are -36 and -2.. thier product is 72 but thier sum is -38..
this one took me time lol
