Answer:
This is a common form of equation known as a difference of squares, it always factors as follows...
(a^2-b^2)=(a+b)(a-b) in this case:
first let's factor out 4...
4(9x^2-25) now factor the difference of squares...
4(3x+5)(3x-5)
Step-by-step explanation:
180 in 40 seconds ; 180/40 = 4.5
<h2>
4.5 feet per minute</h2>
For 30 seconds, divide by 2.
<h2>

Answer:
C. (3,-3)
Step-by-step explanation:
5x + 3y = 6
5(3) + 3(-3) = 6
15 + (-9) = 6
therefore point lies on the line
It’s an example of a central angle
