Question

15n^2-n-28
factored
with work

Answer 1

n- /15 ; n+ /15

15(28) = 240+320+50 = 700

Answer 2

1,700; 2,350; 4,125; 5,120, 10; 60, 20; 30 will work

Answer 3

30 and 20 will not work; thats 10 not 1 lol

n- 30/15 ; n+ 20/15

n- 2 ; n+ 4/3

n- 2 ; 3n+ 4

Answer 4

14,50; 28,25..soo close

Answer 5

n(n+1) = 700

n^2 +n -700

n= -1/5 +- sqrt(2801)/2

Answer 6
