<u>The Difference of Squares</u>
Any difference of two squared monomial results in a factored form like shown below:
Similarly:
For a product of binomials to be a difference of squares, they must be in the described form.
------------------------
(x-y)(y-x) can be rewritten as:
-(x-y)(x-y)
Since both binomials are identicals, the product will not result in a difference of squares.
-----------------------
(6-y)(6-Y)
Since both binomials are identicals, the product will not result in a difference of squares.
-----------------------
(3+xz)(-3+xz) can be rewritten as:
(xz+3)(xz-3). This product is a sum multiplied by a difference of the very same terms, thus the result is a difference of squares:
-----------------------
. This product is a sum multiplied by a difference of the very same terms, thus the result is a difference of squares:
-----------------------
Summarizing:
(3+xz)(-3+xz)
Actually Welcome to the Concept of the Volumes.
Volume of cuboid= L*B*H
here, L=B=20cm and H=10cm
hence , we get as,
Volume = 20*20*10 => Volume = 4000 cubic cm.
hence the volume is ===> 4000 cm^3.
Answer:
March he sells 51. April he sells 107
Step-by-step explanation:
In jan he made 14 so we double that for feb and have 28.
From that 28 he takes home 5 so we are left with 23.
Then we double 28 for March to get 56 but he takes 5 home which leaves 51 to be sold and so on.
The radical equation that has an extraneous solution is 5✓x + 10 - 15 = 30
<h3>How to calculate the equation?</h3>
Based on the information given, the radical equation that has an extraneous solution is 5✓x + 10 - 15 = 30.
This will be:
5✓x + 10 - 15 = 30
Collect like terms
5✓x = 30 - 10 + 15
5✓x = 35
✓x = 35/5
✓x = 7
x = 7² = 49
The equation that does not have an extraneous solution will be ✓x + 1 + 7 = 4. Here, ✓x = -4 and has no solution.
