Mr. curtis built a toolbox for each of his four sons. he as $50 to spend to equip each box. he plans to purchase up to 5 items for each box, and all four boxes must have the same tools.

Curtis needs to determine the relative densities of four different liquids. He measures the volume of each liquid using a graduated cylinder, and measures the mass of each liquid using a balance. Then he records the measurements in the table below.  

Mass (grams)

Volume (ml)

Liquid A

11.8

15.5

Liquid B

17.3

29.8

Liquid C

15.7

19.4

Liquid D

21.4

27.5

so it has to be liquid B

Step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
