Answer:
B is correct.
Step-by-step explanation:
Quadratic Expression (Standard Form) is:
![\displaystyle \large{a {x}^{2} + bx + c}](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20%5Clarge%7Ba%20%7Bx%7D%5E%7B2%7D%20%20%2B%20bx%20%2B%20c%7D)
To say it simply, the expression must have 2 as the highest degree.
This means that if there are any higher or lower degrees than 2 then they are not quadratic expression.
A choice is not quadratic expression because it has 1 as the highest degree.
B choice is correct because 2 is the highest degree.
C choice is wrong because 3 is the highest degree.
D choice is wrong because it is not a polynomial.
Therefore, B is correct.
Answer:
Step-by-step explanation:
Sum of interior angles of a triangle is 180
- 17x + 12x - 8 + 8x + 3 = 180
- 37x - 5 = 180
- 37x = 185
- x = 185/37
- x = 5
Find each angle measure
- m∠A = 17*5 = 85°
- m∠B = 12*5 - 8 = 52°
- m∠C = 8*5 + 3 = 43°
9.1 is probalby the number you are looking for
The answer is p=5/3 hope that helps
