It is not composite because nothing times itself equals 43. It is prime though which means that nothing times itself equals it. So that means that it is not composite it is prime.

Emily knows that the area of a rectangle is 54x9y8 square yards and that it’s length 6x3y4 yards. If she divides the area by the

Furkat [3]

Answer:

Width of the rectangle is: $\mathbf{Width= 9x^6 y^4}$

Option C is correct.

Step-by-step explanation:

Area of rectangle = $54x^9y^8$

Length of rectangle = $6x ^ 3y^4$

We need to find width of rectangle.

The formula used is:

$Area\:of\:rectangle=Length\times Width\\Width=\frac{Area\:of\:rectangle}{Length}$

Putting values in the formula to find Width of rectangle

$Width=\frac{Area\:of\:rectangle}{Length}\\Width=\frac{54x^9y^8}{6x^ 3y^4}$

Using the exponent rule: $\frac{a^m}{a^n}=a^{m-n}$

and simplifying the terms we get

$Width=\frac{54x^9y^8}{6x^3y^4}\\Width=9x^{9-3} \: y^{8-4}\\Width=9x^6 y^{4}$

So, Width of the rectangle is: $\mathbf{Width= 9x^6 y^4}$

Option C is correct.

I believe the percentage of this is 50%. Half the numbers are even, and half are odd. Your fraction is
$\frac{6}{12}$
Simplified, that's a 50% probability.

Hello can you please help me posted picture of question

ollegr [7]

The correct option is (B) 4x^2 + 18x + 18

Explanation:
The area is given as:
(3+2x)(6+2x)

To find the polynomial just simplify it.
3(6+2x) + 2x(6+2x)

18 + 6x + 12x + 4x^2

4x^2 + 18x + 18
