Answer:
196
Step-by-step explanation:
The discriminant (Δ) is given by:

Where the polynomial is in the form:

In this problem, a = 1, b = 0, and c = -49. Thus, plugging it into the formula:

Thus, the discriminant of x² – 49 = 0 is 196.
-3x to the second power - 2
I believe this is your answer.
18/12= 1.5
24/15= 1.6
1.6+1.5=3.1
I think D is your answer
Answer:
The correct option is 4
Step-by-step explanation:
The solution is given as

Now for the initial condition the value of C is calculated as

So the solution is given as

Simplifying the equation as

So the correct option is 4
Answer:
CD = 5
Step-by-step explanation:
AC = 5
BC = 7
∆ACB ≅ ∆DCE, therefore,
AC = CD,
BC = CE, and,
AB = DE
Thus,
AC = CD = 5
CD = 5
