I assume you mean divide using the conjugate to rationalize the denominator and express the result in standard rectangular form.

The method used is Distributive Property.
<h3>What is Distributive property?</h3>
The Distributive Property is an algebraic property that is used to multiply a single value and two or more values within a set of parenthesis.
Given:
(2x² - 1)(3x+2) = (2x²)(3x) + (2x²)(2) + (-1)(3x)+(-1)(2)
Here the property used is Distributive property.
Because distributive property in this way
a*(b+c)= a*b+ a*c
This is how a is being multiplied by with b and c.

Answer:
40 inches
Step-by-step explanation:
if 25 cm = 10 in.
the closest of 105 that can divided by 25 is 100
100/25 is 4
so 4 in. is the answer
Answer:
The answer to your question is: 54°F
Step-by-step explanation:
Data
Ti = 78°F
Initial hour = 2:00
Temperature drops 4°F every hour
Temperature at 8:00 = ?
Process
2:00
3:00 78-4 = 74°F
4:00 74-4 = 70°F
5:00 70-4 = 66°F
6:00 66-4 = 62°F
7:00 62-4 = 58°F
8:00 58-4 = 54°F
Answer: b and e
