Which of the following represents the factorization of the binomial below? 49x2 - 81y2
A. (x-9y)7x-9y)
B. (7x+9yX(7x+9y)
C. (7x+y)(x-97)
D. (7x+9y)(7x-9y)

D

Step-by-step explanation:

49x² - 81y² ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b) , thus

49x² - 81y²

= (7x)² - (9y)²

= (7x + 9y)(7x - 9y) → D

Answer D is correct

Step-by-step explanation:

hope this helps

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.
