Step-by-step explanation:
The percentage of male students is 37.5%
- There for every five girls there are three boys.
- That is eight students per.
- I took two hundred and divided it by eight to get twenty-five.
- I got twenty five, if you take twenty-five times three you get seventy-five & if you take twenty-five times five you get one hundred twenty-five.
- Add those two products and you'll have your two hundred.
- So, take seventy-five over two hundred to get thirty-seven and a half.
- Divide that by one hundred to get the ratio.
- It comes out to 37.5%
The term that must be added to the equation x2+4x=1 to make it into a perfect square is 4.

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
