Answer: Universal set

Step-by-step explanation:

A universal set is usually represented by U and it is set that has all the elements of a related sets.

For example, if there are two sets which are X and Y. Let's say X = {1,2,3} and Y = {1,a,b,c}, therefore, the universal set will be U = {1,2,3,a,b,c}.

In the above scenario, H(...-2,-10,1,2,...3) is a Universal set.

The expression (x+j)(x-j)(x-k) can be rewritten as x^3-5x^2-4x+t, where j,k, and t are constants. Which of the following is the

kirza4 [7]

The correct option is: 20

Explanation

The expression $(x+j)(x-j)(x-k)$ can be rewritten as $x^3-5x^2-4x+t$

That means: $(x+j)(x-j)(x-k)= x^3-5x^2-4x+t$

Now simplifying the left side, we will get....

$(x+j)(x-j)(x-k)= x^3-5x^2-4x+t\\ \\ (x^2-j^2)(x-k)= x^3-5x^2-4x+t\\ \\ x^3-kx^2-j^2x+j^2k= x^3-5x^2-4x+t$

Now comparing the co-effcients of like terms in left and right side, we will get.....

$k=5, j^2=4 \\ \\ and\\ \\ t=j^2k\\ \\ So, t= (4)(5) =20$

Thus, the value of 't' will be 20.

Which expressions are equivalent to 3-8 over 3-4

JulsSmile [24]

Answer:

Either one of $\frac{3-8}{3-4}= \frac{-5}{-1}=\frac{5}{1}=5$ .

Step-by-step explanation:

The easiest way to start off is to evaluate those arithmetic operations:

$\frac{3-8}{3-4}= \frac{-5}{-1}=\frac{5}{1}=5$

And all 4 of these are valid expressions equuivalent to the original.
