<h2>Answer: <em>x = 7.5</em></h2>

<em />

Step-by-step explanation:

Use the Pythagorean Theorem ( a^{2}+b^{2} =c^{2} )

The longest side is <em>c = the hypotenuse</em>, and <em>a and b = the other sides</em> of the triangle.

a = 4                              First: 4^{2}+x^{2}=8.5^{2}

b = x                         Second: 16+x^{2}=72.25  

c = 8.5                          Third: x^{2}=56.25

                                  Fourth: x=\sqrt{56.25}

                                      Fifth: x = 7.5

3(3 - 8x) - 1 = -6x - 28
Wewaii [24]

Answer:

x=2

Step-by-step explanation:

3(3 - 8x) - 1 = -6x - 28

Distribute

9 -24x -1 = -6x -28

Combine like terms

8 -24x = -6x -28

Add 24x to each side

8-24x+24x = -6x-28+24x

8 = 18x-28

Add 28 to each side

8+28 = 18x-28+28

36 = 18x

Divide each side by 18

36/18 = 18x/18

2 =x
