<h3>What is unit conversion?</h3>

Unit conversion is a multi-step process that involves multiplying or dividing by a numerical factor and, more specifically, a conversion factor.

The process may also necessitate selecting the appropriate amount of significant digits and rounding.

Different conversion units are employed to measure various parameters.

Measuring Temperature
Measuring Length
Measuring Capacity
Measuring Weight

Conversion of units is defined as the process of converting between different units & measurements of a given quantity using multiplication or division.
Conversion is the method of changing the amount of one form in terms of mathematics, such as inches to millimeters or liters to gallons.
Units are used in the measurement of length, weight, capacity, temperature, and speed.

Solve the equation and this is an assignment btw

lilavasa [31]

Answer:

z=6 and z=-6

Step-by-step explanation:

$7z^2=252$

Divide both sides by 7

$\frac{7z^2}{7} =\frac{252}{7} \\z^2=36$

Find the square root

z=±√36

z=±6

Therefore, z=6 and z=-6.
