Answer:

The expression is not completely factored.

Step-by-step explanation:

The expression of ${x}^{2} - 4$ can be broken up into two binomials:

$[x - 2][x + 2]$

Together, you have this:

$3[x - 2][x + 2]$

** There is alot of missing information to this question, but at least you know how to work this out.

What is X divided by 5 if X=5?

Paraphin [41]

If you divide X which is 5 by 5, then you will get 1.

5^1 will be 5.

5 divided by 0 does not have a solution. It is not a number.

It is possible to subtract an integer with a negative sign from another number, for example 5-(-3). Multiplying two negative signs will make the sign positive, so the problem would then be this: 5+3. That equals 8.

1+1-1x1/1= 1

Zepler [3.9K]

Answer:

profit : RS 150 and profit % : 3%

Step-by-step explanation:

for profit 10% for loss 4%

s.p will be 2750. s.p will be 2400

Total s.p : 2750 +2400. total s.p : 5150

profit = s.p-c.p. profit%=?

=5150-5000. profit = p /c.p × 100

=150 = 150/5000×100

= 3%
