the length of a rectangle is 4 meters longer than the width. if the area is 22 square meters , find the rectangle dimension
Readme [11.4K]

Let breadth be x

  • Length=x+4

We know

\boxed{\sf Area_{(Rectangle)}=Length\times Breadth}

\\ \sf\longmapsto x(x+4)=22

\\ \sf\longmapsto x^2+4x=22

\\ \sf\longmapsto x^2+4x-22=0

  • By solving

\\ \sf\longmapsto x=-2\pm\sqrt{26}

It doesnot have any real roots

Find greatest 3 digit number divisible by 8,10,12
schepotkina [342]
The greatest 3 digit number divisible by the 8, the 10, and the 12 is 960. The simplest way of finding the number is to multiply all the divisible factor which is the 8, the 10, and the 12 that results in 960 (8*10*12). If this multiply operation results in more than 3 digit number, therefore we must analyze the factor of the result and eliminate it.

A. Is the sum of two polynomials always a polynomial? Explain
IgorLugansk [536]

Answer:  The answers for both (a) and (b) is YES.


Step-by-step explanation: A polynomial is an algebraic expression containing   two or more algebraic terms, i.e., the sum of several terms that contain different powers of the same variable or variables with real coefficients.

For example, p(x) = 4x²+x+2 is a polynomial in variable 'x'.

(a) Yes, the sum of two polynomials is again a polynomial. For example,

if p(x) = ax² + bx + c  and  q(x) = dx² + ex + f, where, a, b, c, d, e and f are real numbers, then their sum will be

p(x) + q(x) = (a+d)x²+(b+e)x+(c+f), which is again a polynomial in 'x' with real coefficients.

(b) Yes, the difference of two polynomials is again a polynomial. For example,

p(x) - q(x) = (a-d)x²+(b-e)x+(c-f), which is again a polynomial in 'x' with real coefficients.

Thus, the answer is YES.
