If it has no real solutions, that means the graph does not intersect the x axis
since we have ax^2+bx+c=0, the parabola opens either up or down
since the vertex is in the second quadrant (x is negative and y is positive in this reigon) and the graph does not cross the x axis, the parabola must open up
if the value of 'a' is positive, then the parabola opens up
so 'a' must be positive
if it is translated to the 4th quadrant, then the vertex is now below the x axis
it will now have 2 x intercepts because the vertex is in the 4th quadrant and look at a graph of a parabola opening up with vertex in 4th quadrant and seehow many time it crosses the x axis

Step 1: 3245 - 12h
Step 2: 324 = 24 sh
324 24
Step 3: 245 245
Step 4: h-13.5
inches
What is the first error that James made when calculating the height of the cylinder?
In step 1, he substituted into the volume formula incorrectly.
In step 2, he calculated 122 incorrectly. It should be 144 rather than 24.
In step 4, the should have canceled, making the correct answer 13.5 cm.
James calculated the height of the cylinder correctly
Answer:
216
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
let a = 2
b = 5
2a + b
Substituting the values,
=> 2(2) + 5
=> 4 + 5
=> 9
