Answer:
164.4
Step-by-step explanation:
m<ABC = m<ABK + m<KBC
17x + 8 = 42 + 12x - 4
17x - 12x = 42 - 4 + 8 add like terms
5x = 46 divide both sides by 5
x = 9.2 now replace x with 9.2 in 17x + 8
17*9.2 + 8 = 164.4
Answer:
D
Step-by-step explanation:
2x(x^4 + 6x^2 - 27)
x^4 + 6x^2 - 27 = 0
x^2 = y
y^2+ 6y - 27 = 0
(y+9)(y-3) = 0
(x^2+9)(x^2-3) = 0
2x(x^2-3)(x^2+9)
