Hello, It is very simples.
Look it :
Let a^3 - b^3 = ?
Add on both th side -3a^2b + 3ab^2
a^3 -3a^2b + 3ab^2 -b^3 = ?
-3a^2b+3ab^2
The firs equation is = (a - b)^3
Then,
(a - b)^3 = ? + 3a^2b - 3ab^2
Passing -3a^2b + 3ab^2 to the left side:
But changing the sinal
? = (a - b)^3 + 3a^2b - 3ab^2
? = (a - b)^3 + 3ab ( a - b)
Putting (a - b) as commun factor
? = (a - b).[ 3ab + (a - b)^2 ]
As (a - b)^2 = a^2 - 2ab + b^2
Then,
? = (a - b).[ 3ab + a^2 -2ab +b^2]
? = (a - b).( a^2 + ab + b^2)
I hope helps!
Answer:
i think 62.5% I believe sorry if I'm wrong
Step-by-step explanation:
In the given mathematical
value of 51, 487 to round off this number to the nearest thousand, we can
elaborate the number values using the expanded form to clearly see the order
position:
<span><span>1. </span><span> 50, 000 = ten
thousands</span></span>
<span><span>2. </span><span> 1, 000 =
thousands</span></span>
<span><span>3. </span><span> 400 = hundreds</span></span>
<span><span>4. </span><span> 80 = tens</span></span>
<span><span>5. </span><span> 7 = ones</span></span>
Now we can observe the
numerical value of 51, 487 than 1, 000 is the number in which belongs to the
thousands’ position hence since the nearest number is 400 the value will be 51,
000.
Answer:
The answer is A, B, and D
Step-by-step explanation:
This is really easy, all you have to do is to choose the answers that are less than 1.
Why? because anything less than 1 multiplied by a number gives you a smaller number.
Since C and E are bigger than 1 then they will give you a bigger number than 2/3.
But A, B, and D are less than 1.
So, the answer is A, B, and D
