Answer:
-4x(3x+4)
Step-by-step explanation:
You have to undo the problem, I will show you how this problem looks if you solve it (the answer i guess? id.k it is hard to explain any other way)
So first we use distributive property-
-4x *3x=-12x^2
-4x*4=-16x
-12x^2-16x And now we have the problem we started with!
Hi!
500 grams = 0,5 kilograms => 1 kg = 1000 grams = 2 * 500 grams
For 1 kg we need to buy 2 bags of 500 grams.
For 56kg we need to buy x bags of 500 grams.
x = (56*2)/1 = 112
The answer is : You should buy 112 bags of 500 grams, because 112 * 500g = 65000g = 65 kg.
Hope this helps!
The answer is C you have to convert 20 % in a decimal 0.2

We are given function: y= 
Where, x is the number of hours after 5a.m.
We need to approximates the number of people standing in line to catch a commuter train at 7 a.m.
From 5 a.m. to 7 a.m. total number of hours = 7-5 = 2 hours.
So, we need to plug x=2 in the given function.
Plugging x=2 in 
, we get
Let us simplify it now.
2^2= 4.
Therefore,
= -20.524 + 63.642 - 3.333.
= 39.785 or 40 approximately.
Therefore, the number of people in line at 7 a.m. is approximately 40 people.
Option D.40 is correct option.
