Answer:
b = 5
Step-by-step explanation:
The given equation is :
[tex]0.3x^2+5x-7=0[/tex] .......(1)
It is in the form of quadratic equation. The general form of a quadratic equation is as follows :
[tex]ax^2+bx+c=0[/tex] .....(2)
Comparing equations (1) and (2), we get :
a = 0.3, b = 5 and c = -7
Hence, the value of b is equal to 5.
