Answer:
x=0 x=9
Step-by-step explanation:
f(x) = x^3 - 9x^2
Set equal to zero to find the zeros
0= x^3 - 9x^2
Factor out x^2
0=x^2 (x-9)
Using the zero product property
0=x^2 0=x-9
x=0 x=9

Answer:
I am not sure but for
CAE it is 65˚
CBD it is 65˚
Step-by-step explanation:
x+40=3x-10
Move the 3x to the other side by subtracting by 3x on both sides
x-3x+40=3x-3x-10
The equation now looks like this:
-2x+40=-10
Move 40 to the other side by subtracting 40 both sides:
-2x+40-40=-10-40
-2x=-50
Divide by -2 on both sides:
-2x/-2=-50/-2
x=25
Since we found out what x is we can replace x in both CAE and CBD:
For CBD: 25+40 is 65
For CAE: 3(25)-10 is 65
