Hi
Just told you : first know by heart remarkable identities !
Then apply :
4x²-12x = -9
4x²-12x +9 =0
(2x-3)² = 0
(2x-3) (2x-3) = 0
Now you have a double solution :
2x-3 = 0
and 2x -3 = 0
I let you try !
Answer:
$405.60
40x13=520
520x.22= 114.4
520-114.4=405.60
Given :
Number of hours studied daily , .
Time given for science and mathematics is , .
To Find :
How much time does she devote for other subjects .
