Answer:
11 weeks
Step-by-step explanation:
34+10x=144 equation
10x=110
x=11
check answer
11*$10=$110 money after 11 weeks at $10/week
+. 34 money saved
=. 144 money needed.
9(x + 1)^4 - 19(x + 1)^2 + 2 = 0
After expanding and re-factoring, we have:
(3x + 2)(3x + 4)(x^2 + 2x - 1) = 0
solutions are x = -2/3, x = -4/3, x = -1 - sqrt(2), x = sqrt(2) - 1
