This is a simple right triangle problem.
a^2 + b^2 = c^2
the hypotenuse (or c) is 9 +x
and a is x
And b is 15
So so we sub in the values
x^2 + (15)^2 = (9+x)^2
x^2 + 225 = x^2 + 18x + 81
144 = 18x
8 = x
Answer: [<em>b + 4 = -10</em>]
Step-by-step explanation: We are given the equation <em>b = -14</em> and told to, given this information, evaluate <em>b + 4 = ?</em> and find <em>?.</em> Given b = -14 we can plug in <em>-14</em> for <em>b</em> in <em>b + 4 = ?</em>. This gives us <em>-14 + 4 = ?.</em> Adding this up gives us the answer of -10. Hope that this makes sense and helps, and good afternoon to you!

Answer:
22.9 m
Step-by-step explanation:
Use cosine law
AB² = 56² + 49² - 2(56)(49)cos(24)
AB² = 523.4625285
AB = 22.9 m
Answer:
18y - 12
Step-by-step explanation:
3(6y - 4)
(3)(6y - 4)
(3)(6y) + (3)(-4)
18y - (3)(-4)
18y - 12
