Answer: M=5.25
Explanation: 5.25•4=21
A= x(4x-2) then distribute the x to get A=4x²-2x
Then plug in the 8 and get A=4(8)²-2(8)
A=256-16
A=240
Answer:
The correct answer is Option A: Multiplication Property of Equality
Step-by-step explanation:
Given equation is:

The given equation is a linear equation in one variable. Different equality properties are used to solve equations like these.
First of all the denominator with 1/5x has to be eliminated for which the whole equation will be multiplied by 5

This property is called multiplication property of equality.
Hence,
The correct answer is Option A: Multiplication Property of Equality
