3x^2−13x+4
Step-by-step explanation:
(x−4)(3x−1)
=(x+−4)(3x+−1)
=(x)(3x)+(x)(−1)+(−4)(3x)+(−4)(−1)
=3x^2−x−12x+4
=3x^2−13x+4
30(30 – x) = 540
distribute
900 -30x = 540
subtract 900 from each side
-30x = -360
divide by -30
x =12
The solutions are where the lines cross each other.
The lines only cross each other once so there is 1 real solution.
