Enter any value of b that will make the following expression factorable
x2 + bx + 13

14

Step-by-step explanation:

?*?=13 and ?+?=b

since 13*1=13, you could replace b with 14, since 13+1=14.

this will factor out into (x+1)(x+13)

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
