Answer:
ok so differnce of 2 perfect ssquares are
x^2-y^2=(x-y)(x+y)
we are given
one factor is 5x-8
remember that all you do is square both terms individually to get them
(5x)^2=25x^2
8^2=64
they are difference so
25x^2-64 is answer
Answer:
C
Step-by-step explanation:
The equation of a line is given by the formula ![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
Where
is the x-coordinate (it is given as 5)
is the y-coordinate (it is given as 1), and
m is the slope (it is given as -3)
Plugging in all the info into the formula we have:
![y-y_1=m(x-x_1)\\y-1=-3(x-5)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29%5C%5Cy-1%3D-3%28x-5%29)
From the answer choices, we see that C is the correct answer.
