Answer:
5.33
Step-by-step explanation:
3x=20-4
3x=16
x=5.33
f(x)=(x+4) ^2 −25
to solve set equal to zero
0 =(x+4) ^2 −25
add 25 to each side
25 = (x+4) ^2
take the square root of each side
square root (25) =(x+4)
+- 5 = (x+4)
5 = x+4 -5 = x+4
subtract 4 from each side
1 =x -9 =x
Answer:
Step-by-step explanation:
They had the same quotient because both of those equations are equal
