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.

Step-by-step explanation:
Area of the sector is 4.71 sq units
Step-by-step explanation:
- Step 1: Area of the sector = Area of the circle × (C/360) where C is the central angle.
Area of the sector = πr²(C/360) = 9π × 60/360
= 9 × 3.14 × 1/6
= 28.26/6 = 4.71 sq units
