Answer:
x = 3/8
Step-by-step explanation:
The difference of the two squares can be found several ways. One way uses the "difference of squares" special form.
a² -b² = (a -b)(a +b)
For the given squares, this is ...
(2x +3)² -(2x -3)² = ((2x +3)-(2x -3))((2x +3) +(2x -3)) = 6(4x) = 24x
We want to find x that makes this difference be 9:
24x = 9
x = 9/24 = 3/8
For the value x = 3/8, the difference between the squares of the binomials will be 9.

Answer:
y=-.3x-7
Step-by-step explanation:
So, if you want to find a line perpendicular to another line, you have to put a decimal in front, or make it a reciprocal. In this case, I put a decimal in front to make it both perpendicular, and cross through (6, -9). Nice.
