Answer :
C
Step-by-step explanation:
- (a+b)(a-b) = a² - b²
- a( b + c) = ab + ac
- a (b - c) = ab - ac
- a( b + c) + d( b + c) = (a + d) (b + c)
3x – 5 + 23x – 9 = 26x - 14
2 . 13x = 26x
2. -7 = -14
2 ( 13x -7) so answer is C
or another way :
a. 2(14x -6) = 28x - 12
b. 3x(13x-6) = 39x² - 18x
c. 2(13x -7) = 26x - 14
d. 3x(13x - 5) = 39x² -15x
so answer is C
Hope this helps ^-^
