Answer:
--3 ±sqrt((-3)^2 -4(4)(-9))
-------------------------------
2(4)
Step-by-step explanation:
4x^2-5=3x+4
We need to get this in standard form to answer the question
Subtract 3x from each side
4x^2-3x-5=3x-3x+4
4x^2-3x-5=+4
Subtract 4 from each side
4x^2-3x-9 =0
a = 4
b = -3
c = -9
-b ±sqrt(b^2 -4ac)
---------------------------
2a
--3 ±sqrt((-3)^2 -4(4)(-9))
-------------------------------
2(4)

Step-by-step explanation:
Hello there!
Use the Pythagorean Theorem;
![a^2+b^2=c^2\\14.4^2+b^2=29^2\\\\B^2=\sqrt{633.64} \\B=25.172](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2%5C%5C14.4%5E2%2Bb%5E2%3D29%5E2%5C%5C%5C%5CB%5E2%3D%5Csqrt%7B633.64%7D%20%5C%5CB%3D25.172)
There you are!
