which of the following is a Pythagorean triple? A. (2 , 2 , 4)
B. (3 , 4 , 5)
C. (6 , 8 , 12)
D. (4 , 5 , 6)

B. (3,4,5)

Step-by-step explanation:

5^2= 4^2 + 3^2

B (3,4,5)

Step-by-step explanation:

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.
