Total = Principal * ((1 + rate/n)^(n*years)
Total = 3,000 * (1.04)^20

The term that must be added to the equation x2+4x=1 to make it into a perfect square is 4.
<h3>
What is Quadratic equation?</h3>
Any equation that can be rewritten in standard form as where x represents an unknown, a, b, and c represent known numbers, and where a 0 is true is a quadratic equation. Since there is no ax2 term, the equation is linear if a = 0, not quadratic.
<h3>
Why is it called a quadratic equation?</h3>
This is true because the Latin word quadratum, which means "square," plus the fact that the area of a square with side length x is equal to x2, make up what is known as the quadratic (or "square-like") definition of a polynomial equation with exponent two.
<h3>According to the given information:</h3>
x²+4x=1
as, the x has coefficient 4.
so,
half the coefficient of x and add and subtract the square of the remaining.
x²+4x + 2 ² - 2² =1
Now,
make the whole square term
x²+4x + 2 ² - 4 - 1=0
( x + 2)² -5= 0

The answer is y=x^2+15x/2-4.
Answer:
A
Step-by-step explanation:
Two vertical then probably two horizontal
The answer is C. It is nonlinear because the increase in the “total house built” compared to the increase in the “months passed” does not show a constant rate of change.
