X-intercepts if f(x) = 0
f(x) = x(x + 1)(x - 5)(x - 7)
f(x) = 0 if x = 0 or x +1 = 0 or x - 5 = 0 or x - 7 =0
Answer: {-1 or 0 or 5 or 7}
Answer:
b = t + 45
Step-by-step explanation:
Position of hot air Ballon = 45 meters above tall seat building ;
Height of tall seat building = t

Answer:
22.5
Step-by-step explanation:
you have to do opposite bedmass to isolate the variable. the opposite of multiplying is division.
<u>(X+2)2</u> <u>=49</u>
2 2
Then do addition as subtraction.
X+2= 24.5
-2 -2
X= 22.5
30= 3*10
30= 3*2*5
48= 12*4
48= 3*4*4
48= 3*2*2*2*2
60= 3*20
60= 3*10*2
60= 3*2*5*2
The GCF is 3*2 because all 3 numbers contain a 3 and a 2 in their prime factorizations.
Final answer: 6
