I'm guessing that x2 is an x to the power of 2, so u can rewrite that as:

x^2 - x - 4

from there you can use completing the square, quadratic function, or factoring.

If the x2 is supposed to be 2x then it would just be as follows:

x - 4

ANSWER

Given,

Diameter of the base of the cylindrical container d=56 cm

Hence, radius of the base of the cylindrical container r=

=28 cm

Dimensions of rectangular solid is (32 cm×22 cm×14 cm)

We know that when a body is completely submerged in a container containing water,

the rise in the volume of water in the container is equal to the volume of the body.

Let, the water rises to a height h.

Hence,

Volume of water rises in cylindrical container =Volume of the rectangular solid

πr

h=32×22×14 cm

×(28)

×h=9856 cm

22×784

9856×7

h=4 cm
