I believe it’s C because none of the others are even close and the 3 and 7 add up correctly
Answer:
2 real solutions
Step-by-step explanation:
We can use the determinant, which says that for a quadratic of the form ax² + bx + c, we can determine what kind of solutions it has by looking at the determinant of the form:
b² - 4ac
If b² - 4ac > 0, then there are 2 real solutions. If b² - 4ac = 0, then there is 1 real solution. If b² - 4ac < 0, then there are 2 imaginary solutions.
Here, a = 6, b = -20, and c = 1. So, plug these into the determinant formula:
b² - 4ac
(-20)² - 4 * 6 * 1 = 400 - 24 = 376
Since 376 is clearly greater than 0, we know this quadratic has 2 real solutions.

<u>Answer:</u>
x = 10
<u>Step-by-step explanation:</u>
We are given a diagram with lines AB and CD intersected by a line EH.
Given that the lines AB and CD are parallel, we are to find the value of x.
Since the lines are parallel so the angles are interior alternate angles and are equal to each other.
Therefore, we can write it as:
x = 10
Answer:
65 degrees
Step-by-step explanation:
The angles will sum up to 360, just do 360 - all known angles
360 - 90 - 128 - 77 = 65
