Answer:
The answer is D.
Step-by-step explanation:
3x*3x = 9x^2
3x*2= 6x
5*3x=15x
5*2=10
6x+15x=21x
9x^2+21x+10
Explanation:
The line of the first part of the function, without the restriction of x <=-2:
The line of the second part of the function, without the restriction is:
To graph the full function, we have to draw a line over the green dashed line until x = -2 and then continue drawing but now over the orange dashed line
Answer:
The graph of the function is:

Antti entered a -kilometer race. His goal is to finish in one hour. He starts off sprinting, and completes the first kilometers of the race at an average speed of kilometers per hour.
To achieve his goal of a one-hour finish time, what average speed (in kilometers per hour) must Antti maintain for the last kilometers of the race?
Enter your answer as a number in decimal form, without units.Hint(s):
Answer:
9x + 36, donde x es el primer número
Step-by-step explanation:
Sea "x" un número cualquiera, el consecutivo o sucesor, corresponde al número que va después, se representa como: (x + 1)
Primer número: x
Segundo número: x + 1
Tercer número: x + 2
Cuarto número: x + 3
Quinto número: x + 4
6th número: x + 5
Séptimo número: x + 6
Octavo número: x + 7
Noveno número: x + 8
La suma de 9 números consecutivos, es:
x + (x + 1) + (x + 2) + (x + 3) + (x + 4) + (x + 5) + (x + 6) + (x + 7) + (x + 8)
9x + 36
Espero que esto ayude!!!
