Answer:
17 packets
Step-by-step explanation:
So Tanya needs 130 chocolate bars.
But there is 8 in each packet.
So,
130 ÷ 8 = 16.25
16 packets
As you can see, there is a quarter left of chocolates that she needs (0.25). So what she can do is buy 1 more packet then give the quarter of that packet to the children.
So 16 + 1 = 17 packets
we are given
x^2-4x-5
we can use formula
x^2-(a+b)x+ab=(x-a)(x-b)
so, we have
a+b=4
ab=-5
now, we can solve for a and b
and we get
a=5, b=-1
now, we can plug it in formula
x^2-4x-5=(x-5)(x+1) ............Answer
