The answer is option 1.
Step-by-step explanation:
In order to simplify the expressions, you have to collect like terms :
3a² + 9ab + 5 - 4a² - 4ab + 3
= (3a² - 4a²) + (9ab - 4ab) + (5 + 3)
= -a² + 5ab + 8
<em>You would use AAS because of the fact that there is two angles and the angle where both triangles instersect and create a verticle angle, there is no angle written. It has an angle then another angle then a side. Hope this helps!</em>

Answer: 53
Step-by-step explanation:
They are both right legs. Use a^2+b^2=c^2.
A= 28^2 B=45^2
A= 784 B= 2025. 2025+ 784= 2809 (radical 2809) To simplified is 53
