How to solve X^4-19x^2+48=0
ZanzabumX [31]
Two numbers that add up to -19 and multiply to 48 are -16 and -3:

(x^4-19x^2+48)=0\\(x^2-16)(x^2-3)=0\\(x+4)(x-4)(x^2-3)=0

So, the solutions come from each parentheses:  x+4=0, x-4=0, and x^2-3=0.

x+4=0
x = -4

x-4=0
x = 4

x^2-3=0
x^2 = 3
x = +/- √3

So, the solutions are -4, -√3, √3, and 4.

Karinna's aquarium can hold 80 liters, which is equal to 80,000 cm'. The base measures 100 cm by 40
tresset_1 [31]

Answer:height=20cm

Step-by-step explanation:

Length=100cm

Breadth=40cm

Volume=80 liters which is equal to 80000cm^3

volume=length x breadth x height

80000=100 x 40 x height

80000=4000 x height

Divide both sides by 4000

80000/4000=(4000xheight)/4000

20=height

Height=20cm
