Answer: 0.6
Explanation: You need to divide 3 by 5 and it will give you the answer of 0.6
Since they have to equal each other you can do reverse math, and if I’m not wrong i think its C. x=3
General form is ax^2+bx+c, and to get there we need to factor using FOIL (First Outside Inside Last)
(2x-1)(x+5)
F (2x × x)= 2x^2
O (2x × 5) 10x
I (-1 × x) -x
L (-1 × 5) -5
now add them together
2x^2+10x-x-5
2×^2+9x-5
and because the equation is in the form
ax^2+bx+c b is equal to 9
