For the right triangle shown, the lengths of two sides are given. find the third side. leave your answer in simplified, radical
lisov135 [29]
If c is the hypotenuse and b is the leg, then the third side (a):
a= \sqrt{c^2-b^2}= \sqrt{16^2-9^2}= \sqrt{256-81}= \sqrt{175}=5 \sqrt{7}

If b and с are legs, then hypotenuse (a):
a= \sqrt{b^2+c^2}= \sqrt{9^2+16^2}= \sqrt{81+256}= \sqrt{337}

Solve the equation and graph the solution(s), if possible. 9|4p + 2| + 8 = 35
Cerrena [4.2K]
Solving an equation means finding a value of a variable that make the equation true. This value is called the solution of the equation.<span> A mathematical equation is just like a balanced equation. Both sides of the equation should be equal at all times. </span><span>Whatever we do to one side, has to be done on the opposite side.</span>

9|4p + 2| + 8 = 35 

&#10;9|4p+2|=35-8&#10; &#10;                Subtract \ 8 \ from \ both \ sides
 
9|4p+2|=27&#10;&#10; &#10; 

|4p+2|= \dfrac{27}{9}    Divide \ both \ sides \ by \ 9

|4p+2|=3 

Break \ down \ the \ problem \ into \ these \ 2 \ equations 

&#10;4p+2=3&#10; &#10; 

-(4p+2)=3 

Solve \ the \ 1st \ equation: \ 4p+2=3 

4p=3-2   <span> Subtract \ 2 \ from \ both \ sides 
</span>
4p=1 

p= \dfrac{1}{4}   <span> Divide \ both \ sides \ by \ 4 
</span>
Solve \ the \ 2nd \ equation: \ -(4p+2)=3 

-4p−2=3   Simplify \ brackets 

-4p=3+2      <span> Add \ 2 \ to \ both \ sides 
</span>
-4p=5 

p= -\dfrac{5}{4} 

Collect \ all \ solutions 

p= -\dfrac{5}{4} , p= \dfrac{1}{4}
