Write and solve an equation
2 answers:
Answer: b = -6
Step-by-step explanation: The equation is attached in the image provided.
In this problem, since the variable <em>b</em> appears on both sides of the equation, we want to get the b's on one side and the number on the other.
The easiest way to do that is by subtracting 3b from both sides which gives us 8b = -48. Now just divide both sides by 8 and b = -6.

Answer:
Approximately 14.42
Step-by-step explanation:
All you have to do is use the Pythagorean Theorem! In case you don't remember, it's a² + b² = c², where a and b are legs and c is the hypotenuse.
So...
8² + 12² = c²
64 + 144 = c²
208 = c²
= 14.42
