1. factor completely: 2a^2 + 6a + 18
2. factor completely: 5x^2 − 5
3. factor completely: 3t^3 + 18t^2 − 48t
4. factor completely: 4n − n^3

Step-by-step explanation:

Factor each expression

product =9 and sum =6

3 times 3 is 9

3 plus 3 is 6

2. Factor completely: 5x^2 − 5

GCF is 5

3. Factor completely: 3t^3 + 18t^2 − 48t

product is -16 and sum is 6

-2 times 8 = -16

-2+8=6

4. Factor completely: 4n − n^3

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

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.
