The company paid $2000 for the printer
Step-by-step explanation:
Let x be the price of the printer for which the company bought it.
If x is the price of printer, then 25% of x will be the profit made by the company.
That is:
0.25x
According to the statement,
The cost and profit earned by company are equal to 2500
So,

Dividing both sides by 1.25

Hence,
The company paid $2000 for the printer

Answer:
x^2 +8x
Step-by-step explanation:
2x+x(x+6)
Distribute
2x + x^2 +6x
Combine like terms
x^2 +8x
The goal to proving identities is to transform one side into the other. We can only pick one side to transform while the other side stays the same the entire time. The general rule of thumb is to transform the more complicated side (though there may be exceptions to this guideline).
So I'll take the left hand side and try to turn it into 
One way we can do that is through the following steps:

Since we've shown that the left hand side transforms into the right hand side, this verifies the equation is an identity.
The given expression is

We have to find the discriminant first . And for that, first we need to move whole terms of the left side to right side, that is


The formula of discriminant is

Substituting the values of a,b and c, we will get

And since the discriminant is greater than 0, or it is positive so we have two real roots.
Therefore the correct option is B .
Hey there :)
- tan²x + sec²x = 1 or 1 + tan²x = sec²x
sin²x + cos²x = 1
Divide the whole by cos²x


so

and

so

Therefore,
tan²x + 1 = sec²x
Take tan²x to the other side {You will have the same answer}
1 = - tan²x = sec²x or sec²x - tanx = 1
