A math expression is anything where you take one or more numbers and add them, subtract them, multiply, divide, etc etc
For example, 2+3 is a math expression
To make it an algebraic expression, we replace one of the numbers with a variable. Often this is the letter x. So let's say we replace the 2 with x. That would have the expression turn into x+3. What we're saying is "some number plus 3"
Normally 2+3 = 5 which is a true equation. Replace the 2 with x and we have x+3 = 5. So we're saying "some number plus 3 is 5". You can guess and check to find that the "some number" has to be 2
--------------------------------------
In summary, the expression example was x+3 and the equation was x+3 = 5
Note: an equation is simply two expressions set equal to each other.
Answer:
The answer to your question is: 4a² + 4b² + 8ab
Step-by-step explanation:
Simplify 4(a² + b² + 2ab)
The only step is to multiply 4 by each term
4a² + 4b² + 8ab
Volume of cylinder = πr²h
Volume = 3.14 x 4² x 20
Volume = 1,004.8 m³
When the tank is 60% full, the volume is:
0.6 x 1004.8
= 602.88 m³ of water
<span>In the Franco-Dahomean War in the 1800s, many French soldiers hesitated before attacking the Dahomey Amazons, which led to the death of a large number of French troops. This hesitation may have been due to cultural beliefs about men fighting women. What is your belief about this? How does it apply to current political debates about women serving in the front of ongoing wars?</span>
