Answer:
can you describe it a little better? i cant understand it
Subtract 16 to get
x^2 -25 = 0
Factor this as
(x -5)(x +5) = 0
The zero product property tells you the product will be zero when one of the factors is zero.
For x-5 = 0
x = 5
For x+5 = 0
x = -5
The appropriate choice is
3) x=-5 or x=5

Answer:
Step-by-step explanation:
Is 1.450 correct? 145 would make more sense. I'd even go with 1,450, just for a laugh. I'll assume 1.450 is the correct number here. I'll assume assute the question eventually asks how old are A and B.
A = 49(B)
A+B=1.450
Substitute:
49B+B=1.450
50B = 1.450
B = 0.029
A = 49(B)
A = 49*(0.029)
A = 1.421
