It is certainly possible for a function decreasing over a certain interval to be negative, but no rule that says it must be. On the other hand, where the function is decreasing, the rate of change of the function must be negative.
<span>x^2+4x+3 = (x + 3)(x +1)....these are factors
answer is FALSE. it does NOT have a repeated factor</span>
Let, the number = x
Then, x * 25% = 71
x * 0.25 = 71 [ 25% =0.25 ]
x = 71 /0.25
x = 284
In short, Your Answer would be 284
Hope this helps!
