<h2><u>A is X^3 Y^2.</u></h2>

because 3 x's and 2 y's are being multiplied.

<h3>For this explanation, I will be utilizing the hidden exponent of 1.</h3>

<em><u>You can put a hidden exponent of 1 to each variable without an exponent, and the value will remain the same.</u></em>

Merely add the exponents of the values with the same base number, or coefficient. —> <em>like terms</em>

X^1 times X^1 times X^1 is X^3, and Y^1 times Y^1 is Y^2.

Our final answer is X^3 Y^2.

<h2><u>B is 6X^2 Y^3.</u></h2>

Like the first expression, we can add a hidden exponent to each <u>VARIABLE,</u> not number.

2 times 3 is 6, and X^1 times X^1 is X^2, and Y^1 times Y^1 times Y^1 is Y^3.

Our final answer is 6X^2 Y^3.

A square has an area of 36 m2. The square is scaled in such a way that its area is increased by 28 m2. What is the approximate f
Naddika [18.5K]

Answer:

The length has increased by a factor of 4/3 or 1 1/3

Step-by-step explanation:

To find the initial length.: root 36.

Root 36 = 6

Then to find the increased version, first find the area: 36 + 28 = 64

Now, the length.

Root 64 = 8

To find the factor it increased by:

6x = 8

x = 8/6 = 4/3

The length has increased by a factor of 4/3 or 1 1/3

Which statement shows two polynomials 4x+6 and 2x^2-8x demonstrating the closure property when multiplied?
melisa1 [442]
The correct answer for the given mathematical question above would be option A. The statement that shows two polynomials 4x + 6 and 2x^2-8x demonstrating the closure property when multiplied is that, 8x^3-20x^2-48x is a polynomial. The answer is option A for the given reason: <span>(4x+6)(2x^2 -8x)= 8x^3 -20x^2 -48x</span>

Alice has just discovered base 10 cake! She is delighted with how powerful it is. One day, after nibbling on the cake, Alice rea
Romashka [77]

Answer:

5.38 ounces

Step-by-step explanation:

Given that :

Alice height = 1 mile

Distance of earth to moon = 239000 miles

Number of base 10 cakes required so they Alice's head just touches the moon ;

Using the relation :

Distance = height per ounce * 10^number of ounces

Height per ounce = 1 mile ;

Let number of ounces = n

Hence,

239000 = 1 * 10^n

239000 = 10^n

Take log of both sides

Log(239000) = n

5.3783979 = n

5.3784 = n

Hence, Alice should take 5.38 ounces of base 10 cakes
