Which of the following polynomials is a difference of squares? *
10 points
x^2+16
x^2+6x+9
x^2+5x+4
x^2-9

x² - 9

Step-by-step explanation:

A difference of squares has the form

a² - b²

Thus

x² - 9

= x² - 3² ← is a difference of squares

if this is really you s much. i only have 3 points left and i have 2 questions to ask

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
