Answer:
Step-by-step explanation:
600 divided by 6 = 100
15% of 100 = 15
15 times 6 = 90
600+90 = 690
B^2 - 4ac
(-9)^2 - 4 (2)(9)
= 81 - 72
=9 >0 yet it is a perfect square (3^2 =9)
So , it is 2 real and rational roots
(x-3) ( 2x-3) =0
x = 3 , x = 3/2
Times both side by 12
48+4x=5x-72
120=x
The answer is x-3y=-12 use math-way for this
