Answer:

4x²

Step-by-step explanation:

Normally you would use the exponent → roots rule, but this one simplifies easier without that

(8x)^{\frac{2}{3} }

8 = 2³

so (8x)^{\frac{2}{3} } = (2^{3}x)^{\frac{2}{3}}

then the threes cancel, since one is a 3 and the other one is \frac{1}{3}

so (8x)^{\frac{2}{3} } = (2^{3}x)^{\frac{2}{3}} = (2x)^2

then just square the 2 and the x

(8x)^{\frac{2}{3} } = (2^{3}x)^{\frac{2}{3}} = (2x)^2 = 4x^2

<h3>Answer: 3\sqrt{7}</h3>

3*sqrt(7)

3 times the square root of 7

====================================================

Explanation:

I'm assuming the V stands for square root. You can write sqrt(63).

\sqrt{63} = \sqrt{9*7}\\\\\sqrt{63} = \sqrt{9}*\sqrt{7}\\\\\sqrt{63} = 3\sqrt{7}

The idea is to factor 63 in such a way that one factor is the largest perfect square possible, that way we can pull the root apart to simplify as shown above. The rule I used for the second step is \sqrt{x*y} = \sqrt{x}*\sqrt{y}

Marcus earns 15% commission on his total sales at work.
IrinaVladis [17]

Answer:

Option C

Step-by-step explanation:

Given the following question:

Total cost is $725
15% Marcus makes in commission.

In order to find the answer, we have to find 15% of $725 and that number will be the total in commissions he earned that week.

\frac{15\times725}{100} =15\times725=10875\div100=108.75

Marcus makes "$108.75" or option C in commissions last week.

Hope this helps.

An isosceles triangle has an angle that measures 98°. Which other angles could be in that isosceles triangle? Choose all that ap
Tamiku [17]

an isosceles triangle is a triangle with two twin sides, and therefore two twin angles.

if one angle is 98°, well, we can't have another 98° angle because that makes 98+98 = 196°, and the sum of all interior angles in a triangle cannot be more than 180°.

so the other remaining angles must be the twin smaller angles, namely 180 - 98 = 82, and each twin takes half of that, namely 41°.

Answer:

There are: 3 sandwiches, 2 sides, and 2 drinks.

The chance of a student getting PB&J and Apple Juice is: 1/3 times 1/2, or 1/6.  

The chance of a student getting a lunch that does not include chips is just 1/2, as there are only two side options, chips and cheese sticks.
