Decide whether this statement is always true, never true, or sometimes true, and explain why: In a quadratic equation of the form 0 = ax2 + bx + c, there will be two real solutions if a and c are of opposite signs
Answers
Answer:
Always true
Step-by-step explanation:
Here, we want to evaluate if the given statement is true
The discriminant D can be calculated using the formula;
b^2 - 4ac
if D is greater than 0, then we will have only real roots
In a case where a and c are of opposite signs;
then -4ac will always give a positive value which can be added to b^2
This positive value will ensure that D is greater than zero and hence we can have only real roots
So this assertion is always true if a and c are of opposite signs

P= 2 (l + w)
L = 2w – 4 cm
W =?
Derivation and solution:
34 = 2 (2w - 4) + 2w
34 = 4w – 8 + 2w
42 = 6w 42/6 = w
W = 7 cm
34 = 2l + 2(7)
34 = 2l + 14
2l = 34 – 14
2l = 20
L = 20/2
L = 10 cm

The counts have been recorded in the accompanying table according to pattern and the number of students who selected that pattern is True.
What is a graph?
A graph is a means to visualise a lot of data in a way that makes it simple for the user to grasp all of the information at once. The graph's line is typically a function that tracks the graph.
The name of the colour pattern will be on the x-axis of the bar graph that can best depict the circumstance, and the number of students who selected the pattern will be listed on the y-axis.
The final design must have the smallest candle and should be on the leftmost side of the equation because it is the yellow pattern. While just four students chose the first candle, it should be the second-largest candle. Given that the values of the second and third candles are 6 and 12, respectively. As a result, the third candle's length should be equal to that of the second candle.
Thus, the given statement is True.
