Which of the binomials below is a factor of this trinomial? x2 + 13x + 42

A. x - 7
B. x + 7
C. x + 84
D. x2 + 12

B.

Step-by-step explanation:

To factor trinomials, you need two numbers that multiply together to give you the third term and add together to give you the second term.

What are two factors that multiply to get 42 and add to get 13? These factors are 6 and 7.

Write the factorization as such:

(x+7)(x+6)

(x+7) is choice B.

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
