Answer:

(a) 2021

Step-by-step explanation:

The expression can be simplified.

$\displaystyle\frac{a^4+b^4+2a^2b^2+a^3b+ab^3}{a^2+b^2}+ab=\frac{(a^2+b^2)^2+ab(a^2+b^2)}{a^2+b^2}+ab\\\\=a^2+b^2+ab+ab=(a+b)^2\\\\=(\sqrt{2021})^2=\boxed{2021}$

Write two integers whose products is negative?

yKpoI14uk [10]

Answer:

Any negative integer and any positive integer.

Like -5 and 3.

Step-by-step explanation:

In multiplication, a positive number and a negative number will result in a negative product.

So, you can use any positive integer and multiply it by any negative integer to get a negative product.

Evaluate f(t)=-2t2+ 1 for f(-3).

podryga [215]

Answer:

Step-by-step explanation:

First, plug-in f(-3) into t in the function:

$f(-3)=-2(-3) +1$

Second, multiply -2 and -3 to get 6:

$f(-3)=-2(-3)+1$ ⇒ $f(-3)=6+1$

Third, add 6 and 1 to get your answer:

$f(-3)= 6+1$ ⇒ $f(-3)=7$

Which set of ordered pairs has point symmetry with respect to the origin (0, 0)? (5, 4), (-5, -4) (5, 4), (5, -4) (5, 4), (4, 5)

Sidana [21]

The set of ordered pair that has point symmetry in respect to origin is (5, 4), (-5, -4).

<h3>What is the point of symmetry?</h3>

This is a term that is used to refer to the points that are on the same distance from the origin but are on opposite sides.

The line that connects the points are known to move through the origin such that when measured on the graph, the distances between these points but they are opposite because they are in negatives and positives on the two sides.
