The first one is x=2y plus one.
The second one is
The discriminante :
b^2-4ac
1^2 - 4 * -2 * -28 = 1 - 224 = -223
When the discriminant (b^2-4ac) is less than 0, the equation had no real solutions.
-223<0, so, 2x^2+x-28 = 0 has no real solutions.
Hope that helps :)
Answer:
The diameter is 6
Step-by-step explanation:
the radius is just half of the diameter so 2x3= 6
Answer:
The answer is x=29
