Final Answer: 
Steps/Reasons/Explanation:
Question: Solve by using the quadratic formula:
.
<u>Step 1</u>: Use the Quadratic Formula.
![x = \frac{6 + \sqrt[2]{2} }{2}, \frac{6 - \sqrt[2]{2} }{2}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B6%20%2B%20%5Csqrt%5B2%5D%7B2%7D%20%7D%7B2%7D%2C%20%5Cfrac%7B6%20-%20%5Csqrt%5B2%5D%7B2%7D%20%7D%7B2%7D)
<u>Step 2</u>: Simplify solutions.

~I hope I helped you :)~ The quadratic formulaic is attached in an image.
5y + 7 = 52
5y = 52 - 7
5y = 45
y = 9

=

=
3(x+12) = 2 x 42
3x + 36 = 84
3x = 84 - 36
3x = 48
x = 16
Angle H = 180 - 52 - 36 = 92
Answer:
$1.80
Step-by-step explanation:
4x = 7.20
x = 1.80
