6(y+8) is the answer but you didn’t finish the equation so
In scientific notation: 8.74*10^-7
2x^2 + 10x + 8
=2( x + 1) (x + 4)
2,862 bacteria
6,200/26 = x/12
For one hour, there are 238.461538. Multiply that by 12 and get 2861.53846. Round to the nearest whole number and your answer is 2,862 bacteria.
