Answer:

(B) (7x - 6 ) ( 7x + 6)

Step-by-step explanation:

49x^2 - 36

This is the difference of squares

(7x)^2 - 6^2

We can factor this as

(a^2 -b^2) =(a-b) (a+b)

(7x)^2 - 6^2 = (7x-6) (7x+6)

2x+7=12x-6 looking for x

Rzqust [24]

Hey!

Let's start by writing the problem:
$2x+7=12x-6$
Subtract 7 from both sides.
$2x+7-7=12x-6-7$
$2x=12x-13$
Subtact 12x from both sides.
$2x-12x=12x-13-12x$
$-10x=-13$
Divide both sides by -10.
$\frac{-10x}{-10}=\frac{-13}{-10}$
$x=\frac{13}{10}$

Let me know if you have any questions regarding this problem!
Thanks!
