\Given :

x^{3} +x^{2} -20x

Solution:

x^{3} +x^{2} -20x

taking x common from the given polynomial

⇒x(x^{2} +x-20)=0

⇒x(x(x+5)-4(x+5))=0

⇒x(x+5)(x-4)=0

⇒ x=0 , x+5=0 , x-4=0

⇒x = 0 , x = -5 , x = 4

X + 2y = 200 x = y + 50

Simora [160]

Answer:

x = 100

y = 50

Step-by-step explanation:

if x = y + 50,

putting the value of x in first equation we get,

x + 2y = 200
y + 50 + 2y = 200
3y = 200 - 50
y = 150 / 3
y = 50

putting the value of y in second equation,

x = y + 50
x = 50 + 50
x = 100

What is rational number?</h3>

Rational Numbers: Any number that can be written as a ratio (or fraction) of two integers is a rational number
In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers.
A numerator p and a non-zero denominator.
For example, is a rational number just like any integer (e.g. 5 = the set of all rational numbers, also called "rational numbers", the field of rational numbers, or the field of rational numbers is usually , printed in bold
Rational numbers are real numbers.
This statement is not unique: not only in base 10, but also in other integer bases such as binary and hexadecimal (see Decimal repetition § Extensions to other bases).
