Evaluate 4(3.1+2) 20 20.8 24

20112.25

Step-by-step explanation:

4x(5.3)x 20

 20.3 x 20= 40.3

40.3 x 20.8= 838.24

838.24 x 24= 20112.25

answer is 24 or C on edge !!

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.
