Answer:
B. and C.
Step-by-step explanation:
1. Set the polynomial equal to zero:
x² + 5x + 7 = 0
2. Plug the given values of a, b, and c into the quadratic formula:

3. Solve the square root:



4. Simplify the rest:

5. Separate the solutions:

Thus, options B and C are the answers.

Answer:
740
Step-by-step explanation:
If t represents the number of tents made, then 4.5t represents the amount of canvas needed. We have ...
4.5t = 3330
t = 3330/4.5 = 740
740 tents could be made.
54 - 18n
Multiply -9 by -6 to get 54.
Multiply -9 by 2n to get 18n.
Answer:

5). As x-> -∞, f(x)-> -∞
As x-> ∞, f(x)-> ∞
3). As x-> -∞, f(x)-> -∞
As x-> ∞, f(x)-> ∞
6). As x-> -∞, f(x)-> ∞
As x-> ∞, f(x)-> ∞
Step-by-step explanation:
I just watched a quick video so you can't completely trust me, but i tried my best. Hopefully someone more trustworthy for this comes in.
A= (1/2) b*h
h=3 sqrt3
A= (1/2)*6*3sqrt3
A= 9sqrt3 square inches
