The vertex to this quadratic equation is 2
Parenthasees
the first onewould evaluate to 4x²
the 2nd one would just be -2x²
Answer:
Step-by-step explanation:
a² + b² = c²
a² + 9² = 12²
a² + 81 = 144
a² = 63
a = √63
The area would be 63.The steps to how I got that anwser:
1.] Write your formula
A=bh
----
2
2.]Begin by plugging in your measurements
A=7.5 times 16.8
-------------------
2
3.]Multiply the top two numbers together
A=126
-----
2
4.]Divide to get your final anwser
A=63
