Answer:
<h2><u><em>
x - 15 = 2</em></u></h2>
Step-by-step explanation:
The difference of a number and fifteen is two. Write and Algebra Sentence then solve the number.
x - 15 = 2
x = 2 + 15
x = 17
-------------------------
check
17 - 15 = 2
2 = 2
<u>the answer is good</u>
The answer is 3 because it goes into 39 and 42 and 6 doesn't go into 39
144+64= 178

a^2+b^2= c^2
Whenever finding a missing length use the formula up above :
a^2+b^2= c^2
a^2-b^2= c^2
144-64= 80

Answers are 13.3 and 8.9
Fx = 12 I did the first one
Answer: 
Step-by-step explanation:
Add 2 to both sides of the equation and divide both sides of the equation by 15. Then:

Apply base 8 to both sides of the equation:

Solve for "x", then you get:
![-2x-7=8^{\frac{1}{3}}\\\\-2x=\sqrt[3]{8}+7\\\\ x=\frac{\sqrt[3]{8}+7}{-2}\\\\x=-4.5](https://tex.z-dn.net/?f=-2x-7%3D8%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%5C%5C%5C%5C-2x%3D%5Csqrt%5B3%5D%7B8%7D%2B7%5C%5C%5C%5C%20x%3D%5Cfrac%7B%5Csqrt%5B3%5D%7B8%7D%2B7%7D%7B-2%7D%5C%5C%5C%5Cx%3D-4.5)
