(-3 - 5i )(-3 + 5i ) = -16 34 34 - 30

Answers

You can use:

(a-b)(a+b)=a^2-b^2

We know:

i=√(-1)\to i^2=-1

Calculate:

(-3-5i)(-3+5i)=(-3)^2-(5i)^2=9-25i^2=9-25(-1)=9+25=34

Answer:

(-3 - 5i )(-3 + 5i ) = 34 , I'm pretty sure 34 is the answer.

How is a table helpful when constructing equations

Answers

Its helpful because it gives you the number to put in and to find the unit rate

Final answer:

Tables aid in constructing equations by facilitating the organization and visualization of mathematical data. This makes it easier to apply given parameters to equations and to understand their behavior. For instance, an equilibrium state can be visually represented in a table.

Explanation:

A table is incredibly helpful when constructing equations because it aids in the organization and visualization of mathematical data. Through the usage of tables, one can clearly list and categorize known values that might be used in an equation, thereby making it easier to identify what needs to be solved. For instance, if you're given multiple variables and constants in a word problem, a table can be used to order these parameters systematically so they can be more easily applied into constructing equations.

Similarly, tables contribute to expressing equations visually as they can illustrate changes in variable values, which can further assist in understanding the behavior of the equation. An equilibrium state, for instance, can be clearly italicized in a table to visually represent the point where an equation balances, which would be harder to see in text form.
