Answer:
c. 25
Step-by-step explanation:
BOTH SIDES HAVE X SO YOU PUT THEM IN A 1 EQUATION WAY AND SOLVE X:
4X+1=2X+23
4X-2X=23-1
2X=32
X= 32/2=11
THEN YOU GO TO THE BASE AND CHANGE X AND SOLVE THE EQUATION WITH X=11
3x11-8
33-8= 25=BASE

<span>Finding the square root.</span>
Answer: 0, 4, -9
Set the equation equal to zero.
x(x - 4)(x + 9) = 0
Solve for x by setting each factor equal to zero.
The factors in the equation are x, (x - 4), and (x + 9).
x = 4
x = -9
The zeros of the function are 0, 4, and -9.
