Answer:
x = 4
Step-by-step explanation:
3 x ( 4x -7 ) = 27
3 x 4x = 12x
3 x -7 = -21
12x -21 = 27
12x -21 + 21 = 27 + 21
12x = 48
12x/12 = 48/12
x = 4
Answer:
x = -1 or
x = -7
Step-by-step explanation:
Given DAB and BCD are similar :
2x^2 + 7 = x^2 - 8x make the left side of equation 0 by exporting all terms to right side
2x^2 - x^2 + 8x + 7 = 0 add like terms
x^2 + 8x + 7 = 0
(x + 1) * (x + 7) = 0 in this case x is either -1 or -7
