Answer:

The answer is 3) 40.

Step-by-step explanation:

since you're working with the Pythagorean theorem, you should know that a^2+b^2=c^2, therefore, we know that we only have two sides. we have a and c. we know that a = 42 and c = 58, giving us the equation of 42^2+b^2=58^2,

we want to find b!

so we would simply subtract the two.

58^2 - 42^2 = b

b = 1600

now we want to square root,

b = sqrt1600

which in the end, gives us the answer of 40.

<em>∙•❁ </em>Okay time to solve this Step-By-Step.<em>❁•∙ </em>

16−<span>2n</span>−5+<span>8n</span>=<span>65

<em>∙•❁ </em>So the first part we need to Simplify both sides of this equation, so:

<span><span><span><span>16−<span>2n</span></span>−5</span>+<span>8n</span></span>=65

<em>∙•❁ </em>We are going to simplify this Step-By-Step.

<span><span><span><span>16−<span>2n</span></span>−5</span>+<span>8n</span></span>=65

</span><span><span><span><span><span><span>16+</span>−<span>2n</span></span>+</span>−5</span>+<span>8n</span></span>=65

<em>∙•❁ </em>Combine like terms:
</span><span><span><span><span>
(<span><span>−2n</span>+8n</span>)</span>+<span>(<span>16+−5</span>)</span></span>=65 </span>

<span><span>6n+11</span>=65

</span><span><span><span>6n</span>+11</span>=65

<em>∙•❁ </em>Now subtract 11 from both sides.

<span><span><span><span>6n</span>+11</span>−11</span>=<span>65−11

</span></span><span><span>6n</span>=54

<em>∙•❁ </em>Now divide both sides by 6 and you'll get your answer:

6n/6=54/6

<em>∙•❁ </em>Your final answer is:

n=9

<em>∙•❁I hope this helps!❁•∙ </em> </span></span></span></span></span>
