Answer:
12x+21
Step-by-step explanation:i think this might be it im not 100% sure but im trying
(6,-3) m=-3
formula is y=mx+c
substitute: -3= 3(6)+c
-3=-18+c (takeaway 18 from both sides)
-15=c
Rewrite equation in form y=mx+c
Therefore answer is y=-3x-15
I think this is how u do it from what I can remember :)
The first people cuz of the formula
Answer:
(7w + 9x)(7w - 9x)
Step-by-step explanation:
Given expression;
49w² - 81x²
Now to solve the problem;
49w² - 81x² = 7²w² - 9²x²
Using differences of two squares;
x² - y² = (x + y)(x - y)
So;
7²w² - 9²x² = (7w + 9x)(7w - 9x)
Option C, 36, because it is the LCM (Least common multiple)
