(x^2 + 3)(5x + 9)
5x^3 + 9x^2 + 15x + 27
Answer: $45451
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = 25000
r = 3% = 3/100 = 0.03
n = 4 because it was compounded 4 times in a year.
t = 20 years
Therefore,
A = 25000(1+0.03/4)^4 × 20
A = 25000(1+0.0075)^80
A = 25000(1.0075)^80
A = $45451
The answer would be C because the inequality is greater than 70 but less then 80.
This is a way to factoring trinomials (there exist different equivalent methods).
Multiply the trinomial but the term accompanying . This is the second line. Then, you could take the square of the 
, ant try to create a factor () () that will correspond to the expression in the second line. That is, we want 
In ? we put the corresponding numbers that, if we multiply them we will obtain 42, and if we add them we will obtain 13. This numbers are 6 and 7. Then, we have 
The last step is divide by the number that we multipy in the first step.
The correct answer for the completion exercise shown above is: sine.
Therefore, the complete text is shown below: "<span>In a right triangle, the sine of an angle can be found by dividing the length of the opposite leg by the length of the triangle's hypotenuse".

A right triangle is a triangle that has an angle of 90 degrees.
The sine is one of the most common trigonometric functions. Therefore, you have that the sine of an angle is:
Sin(α)=opposite/hypotenuse
