For this standard for, a = -1, b = 0 and c = 18.
In order to find this, you must first multiply the two parenthesis by each other.
(5 + x)(5 - x)
25 + 5x - 5x - x^2
25 - x^2
Now we need to set it equal to the other side and solve for 0.
25 - x^2 = 7 ----> subtract 7 from both sides.
18 - x^2 = 0 -----> now readjust the order
-x^2 + 18 = 0
So, once we've reached here, the a value is always the coefficient of the x^2 term (-1), b is the value of the coefficient of the x term (0) and c is the constant (18).
The ratio would be 36 to 18
because 9*4=36
and 18 is 18 lol
so (calculator) 1,080/9=120
120
20*18=180
100*9=900
so
idek man this is hard as hell,I tried tho,try to do the rest of the problem from what I have set up
