Select the expression that is equivalent to: 3 root 1089

Delicious77 [7]

Answer:

$3\sqrt{1089}=3\sqrt{3^2(11)^2}$

Step-by-step explanation:

Given : Expression $3\sqrt{1089}$

To find : Select the expression that is equivalent to expression ?

Solution :

Re-write the expression as,

$3\sqrt{1089}=3\sqrt{3\times 3\times 11\times 11}$

$3\sqrt{1089}=3\sqrt{3^2\times 11^2}$

$3\sqrt{1089}=3\sqrt{(3\times 11)^2}$

$3\sqrt{1089}=3\sqrt{(33)^2}$

$3\sqrt{1089}=3\times 33$

$3\sqrt{1089}=99$

The above are the possible equivalent expressions.

Solve and show your work for each question.

Harlamova29_29 [7]

Answer:

9/20

Step-by-step explanation:

You set the fraction up at first as 45/100. Then you know that 5 goes into each so you divide by 5 $\frac{45}{100} /5$

45/5=9

100/5=20

You get 9/20, and this is in simplest form.

ss7ja [257]

Answer:

a difference of squares

Step-by-step explanation:

Let's write down the expression:

$(a^2)^2 -(b^2)^2$

we can see that this expression is one of the form $x^2 -y^2$ which is the general expression of a difference of squares.

To be more specific and to see why we say this, let's make $x=a^2$ and $y=b^2$

Now, if we substitute this in the general formula, we get:

$x^2 -y^2 =(a^2)^2 -(b^2)^2$

Thus, this expression is a difference of squares.

What is the domain of the function on the graph?

Dennis_Churaev [7]

Answer:

All real numbers greater than or equal to -3

Step-by-step explanation:

First look at graph where the line points to which direction of the graph

And look for any closed or open circles in the graph

Since in the graph has a close circle at (-3,-2) meaning it includes that x-value for its domain.

With the graph going to positive infinity it states that the domain is all real numbers.

So in conclusion it has a domain of all real numbers greater than or equal to -3
