Use the square root property to solve x^2-9=0
Please help and please show work if you can

x = 3 or -3

Step-by-step explanation:

So you have the equation x² - 9 = 0

Move the 9 to the other side: x² = 9

Then take the square root of both sides: = ±

x = ± = ±3

x = 3 or -3

(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.
