Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~

Question like this are fairly simple...

The one thing you should know, is when ever you deal with questions like this, always go to your calculator first...

But... I will help you with this one...

We know:

9^15 = 205891132094649

3^27 = 7625597484987

So, what is (9^15) / (3^27)???

Well we pull out our calculator, and enter it in, and we get: 27

So...

The answer is: 3^27 is 27x smaller than 9^15

Which of the following is the square of a binomial?

Advocard [28]

ANSWER

$16 {x}^{2} + 24xy + 9 {y}^{2}$

EXPLANATION

We want to find the expression which is a square of a binomial.

In other words, we want to identify the expression which is a perfect square trinomial.

$16 {x}^{2} + 24xy + 9 {y}^{2}$

This expression can be rewritten as,

${(4x)}^{2} + 2(4 \times 3)xy + {(3y)}^{2}$

This is a perfect square trinomial that can be factored as:

${(4x)}^{2} + 2(4 \times 3)xy + {(3y)}^{2} = (4x + 3y) ^{2}$

This is the square of a binomial.

The correct answer is D

Calculate the distance between (4,9) and (-2,6) using the distance formula.

MAVERICK [17]

Answer:

$\large\boxed{d=3\sqrt5}$

Step-by-step explanation:

$\text{the formula of a distance between two points}\ A(x_1,\ y_1)\ \text{and}\ B(x_2,\ y_2):\\\\|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\=========================\\\\\text{We have}\ (4,\ 9)\ \text{and}\ (-2,\ 6).\ \text{Substitute:}\\\\d=\sqrt{(-2-4)^2+(6-9)^2}=\sqrt{(-6)^2+(-3)^2}=\sqrt{36+9}=\sqrt{45}\\\\\sqrt{45}=\sqrt{9\cdot5}=\sqrt9\cdot\sqrt5=3\sqrt5$

Brian found 12-19 by breaking apart 19 into 12+7 write equations to show how Brian could have found the difference. ?

melomori [17]

Answer:

Answer is 12-19 = -7

Step-by-step explanation:

12- 19 you can break 19 into 12 +7

then

it is easy to find 12-12 = 0

Now subtracts 0 - 7 =- 7

then

break 7 into 3 + 4

then

0 - 3 = -3

-3 - 4 = -7

So ,

12 - 19 = -7
