Answer:
3.95m + 8.95b = 47.65
Why?
It cannot be the first or second equation since the total amount was $47.65, not $60.55 or $47.95.
It’s either the third or fourth equation. You can tell it’s the third one since in the question it states “Let m represent the number of magazines and b represent the number of books.” The fourth equation gets it reversed by saying each magazine costs $8.95 and each book costs $3.95, when in reality it’s the other way around.
Therefore, the third equation most accurately depicts this situation.

Someone help me please
Gemiola [76]

Answer:

x=2\sqrt{6}

Step-by-step explanation:

Use the Pythagorean theorem:

a^2+b^2=c^2

a and b are the legs and c is the hypotenuse. Insert the values:

\sqrt{10}^2+\sqrt{14}^2=x^2

Simplify exponents using the rule \sqrt{x}^2=x :

10+14=x^2

Simplify addition:

24=x^2\\x^2=24

Find the square root:

\sqrt{x^2}=\sqrt{24}\\  x=\sqrt{24}

Simplify in radical form: Find a common factor of 24 that is a perfect square:

\sqrt{24}=\sqrt{4*6}

Separate:

\sqrt{4}*\sqrt{6}

Simplify:

2*\sqrt{6}\\x=2\sqrt{6}

Finito.
