Answer:
B. a = 4, b = -8, c = -3
Step-by-step explanation:
The quadratic equation given is:
![4x^2- 8x = 3](https://tex.z-dn.net/?f=4x%5E2-%208x%20%3D%203)
The general form of a quadratic equation is given as:
![ax^2 + bx +c = 0](https://tex.z-dn.net/?f=ax%5E2%20%2B%20bx%20%2Bc%20%3D%200)
Let us put the given equation in this form and then compare with the general form of the quadratic equation.
![4x^2- 8x = 3\\\\4x^2 - 8x - 3 = 0](https://tex.z-dn.net/?f=4x%5E2-%208x%20%3D%203%5C%5C%5C%5C4x%5E2%20-%208x%20-%203%20%3D%200)
Therefore, by comparing:
a = 4
b = -8
c = -3
The correct option is B
The answer is 5/4 ....so go for that !!! C
Answer:
36
Step-by-step explanation:
![\frac{0.25}{0.75} =\frac{12}{x} \\](https://tex.z-dn.net/?f=%5Cfrac%7B0.25%7D%7B0.75%7D%20%3D%5Cfrac%7B12%7D%7Bx%7D%20%5C%5C)
![0.75 *12=9](https://tex.z-dn.net/?f=0.75%20%2A12%3D9)
![\frac{9}{0.25} =36](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B0.25%7D%20%3D36)
= 9a(5x² + 3x + 2)
The distributive property lets you remove the same factor from all terms and write it outside parentheses.
