Which of the following represents the set of possible rational roots for the polynomial shown below?
2x3 + 5x2 - 8x - 10 = 0
O A. {#1, #2, #4, 5, 10, 20}
O B.
{+3, +2, +1, +2, +3, +}, + }
O.{+, +1, +2, +2, +5, + 10}
e {1,1,2,3,4,5,10,20}

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

320ft

step-by-step explanation:

120 divided by 3 equals 40

40 times 4=160

160 times 2=320
