Find the sum: (x2 + 2x + 3) + (3x2 + x + 1)
a. 3x^4+4x+3
b.4x^2+3x+4
c.4x^3+3x+4
d.4x^4+4x+3

B

Step-by-step explanation:

using the distributive property, only like exponents can be added or subtracted together. (x^2+3x^2)+(2x+x)+(3+1) or 4x^2+3x+4

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.
