which expression is equivalent to( 9x^2+2x-7)(-4)
a.(9x^2+2x-7)(x)+(9x^2+2x-7)(x-4)
b. x(9x^2+2x-7)-4
c.-4x(9x^2+2x-7)
d. x(9x^2+2x-7)+4(9x^2+2x-7)





Respuesta :

Answer:

I'm pretty sure its B. (9x2+2x-7)(x)+(9x2+2x-7)(-4)  

Because its just splitting up the (x-4) and if you add the answers together then you get the same answer as the original

Step-by-step explanation:


Answer:  Option 'b' is correct.

Step-by-step explanation:

Since we have given that

[tex](9x^2+2x-7)(x-4)[/tex]

We need to find the equivalent form:

We will apply "Distributive law":

[tex]a\times b+a\times c\\\\=a\times (b+c)[/tex]

So, it becomes,

[tex]x(9x^2+2x-7)-4(9x^2+2x-7)[/tex]

Hence, Option 'b' is correct.
