Both A and C would be solutions to the equation.
In order to solve for this you must first get the equation equal to 0.
2x^2+5x+8=6 ----> subtract 6 from both sides
2x^2 + 5x + 2 = 0
Now knowing this we can use the coefficients of each one in descending order of power as a, b and c.
a = 2 (because it is the coefficient to x^2)
b = 5 (because it is the coefficient to x)
c = 2 (because it is the end number)
Now we can plug these values into the quadratic equation.





or -1/2 for the first answer

or -2 for the second answer
Answer:
52 cm^2
Step-by-step explanation:
Solve by splitting the figures into 2 parts and finding their areas separately:
Rectangle:
8 × 5 = 40
Triangle:
1/2 × b × h = 1/2 × 8 × 3 = 4 × 3 = 12
Total: 40 + 12 = 52
Answer: 65%
Step-by-step explanation: divide 13/20 and get .65 which is 65%
Answer:
Step-by-step explanation:
4/5 x - 2 > 3/10 * 2x
4/5 x - 2 > 3/5 x
4/5 x - 2 - 3/5x> 0
1/5x > 2
x > 10
