Help me please and dont scam the points
kicyunya [14]

Answer:

So the answer is 14 seconds.

Step-by-step explanation:

Median means the number in the middle, and 17 and 11 are in the middle. Because there's 2 numbers in the middle, you need to average them to find the answer.

17+11=28

28 / 2= 14. So the answer is <u>14 </u><u>seconds</u>.

Solve for 2.<br> -9x +5 &lt; 17 AND<br> 13x + 25 &lt; -1
Elena L [17]

Answer:

no solution

Step-by-step explanation:

-9x +5 < 17 AND   13x + 25 < -1

Solve each part separately and then put back together

-9x +5 < 17

Subtract 5 from each side

-9x+5-5< 17-5

-9x < 12

Divide each side by -9 remembering to flip the inequality

-9x/-9>12/-9

x > -4/3

and

13x + 25 < -1

subtract 25 from each side

13x +25-25 < -1-25

13x <-26

Divide by 13

13x/13 < -26/13

x <-2

There is no overlap so there is no solution

What is the following simplified product? Assume x greater-than-or-equal-to 0 2 StartRoot 8 x cubed EndRoot (3 StartRoot 10 x Su
RideAnS [48]

This is the simplest form 4\sqrt{5}x^3(6\sqrt{x} -\sqrt{2}).

<h2>Exponent</h2>

Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. X is the base and n is the power.

<h3>Simplification</h3>

Simplification is to make something easier to do or understand and to make something less complicated.

Given

\rm 2\sqrt{8x^3} * (3\sqrt{10x^4} - x\sqrt{5x^2}  ) is an expression.

<h3>How to make it simple?</h3>

\rm 2\sqrt{8x^3} * (3\sqrt{10x^4} - x\sqrt{5x^2}  )

On simplifying, we have

\rm 4\sqrt{2}  (x)^{\frac{3}{2}} * ( 3\sqrt{10} x^2 - \sqrt{5} x^{\frac{3}{2}})\\\\24\sqrt{5} x^{\frac{7}{2}}  - 4\sqrt{10}x^3\\\\4\sqrt{5}x^3(6\sqrt{x} -\sqrt{2} )\\

This is the simplest form 4\sqrt{5}x^3(6\sqrt{x} -\sqrt{2}).
