Answer:
x = 0 , -2 , 1 +i√3 ; 1 - i√3
Step-by-step explanation:
2x⁴ + 16x = 0
2x(x³ + 8) = 0
2x(x³ + 2³) = 0
2x (x + 2)(x² -2x + 2²) = 0 {a³ + b³ = (a + b)*(a² -ab +b²}
2x = 0
x = 0
x + 2 = 0
x = -2
x² - 2x + 4 = 0
a = 1 ; b = -2 and c = 4
D = b² - 4ac = (-2)² - 4*1*4= 4 - 16 = -12
root = (-b ± √D)/2a
= (-(-2) ± 2i√3)/2*1
= (2 ± 2i√2)/2

Answer:
4
Step-by-step explanation:
because the variable is h and the constant is 3
3) 1 lb=16 oz. multiply the number of lbs by 16 to get number of oz: 320x16=5,120. Since they want per month divide by 12: 5120/12=426.6667. Rounded to the nearest tenth: 426.7 oz. hope this helps :)
Answer:
9m+4n+5
Step-by-step explanation:
9m
19 - 14 = 5
4n
so we can combined the 9m,5,4n to 9m+4n+5
