Find the TWO integers whos product is -12 and whose sum is 1<br>

ahrayia [7]

Answer:

$\rm Numbers = 4 \ and \ -3.$

Step-by-step explanation:

Given :-

The sum of two numbers is 1 .

The product of the nos . is 12 .

And we need to find out the numbers. So let us take ,

First number be x

Second number be 1-x .

According to first condition :-

$\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}$

Hence the numbers are 4 and -3

Answer:

5391.76

Step-by-step explanation:

We have a rectangle and 2 semicircles

First find the area of the rectangle

A = l*w

A = 44*88= 3872

Then we know that 2 semicircles = 1 circle

The area of a circle is

A = pi r^2

The diameter is 44 so the radius is 22

A = pi * 22^2

A = pi484

A =1519.76

Add the areas together

1519.76+3872

5391.76

What is true about the completely simplified sum of the polynomials 3x squared y squared minus 2 x y to the power of 5 and negat

12345 [234]

Answer:

The sum is a binomial with a degree of 6.

Step-by-step explanation:

To find : What is true about the completely simplified sum of the polynomials $3x^2y^2-2xy^5$ and $-3x^2y^2+3x^4y$ ?

Solution :

The polynomials $3x^2y^2-2xy^5$ and $-3x^2y^2+3x^4y$ ,

The sum of polynomial is given by,

$S=3x^2y^2-2xy^5+(-3x^2y^2+3x^4y)$

On simplifying , we get,

$S=3x^2y^2-2xy^5-3x^2y^2+3x^4y$

$S=-2xy^5+3x^4y$

Therefore, the result obtained is a binomial with a degree of 6.
