Answer:
-4x^2-28x
Step-by-step explanation:
Distribute
-4x(x) and -4x(-7)
-4x^2 and -28x
6 hikers = 4.5 lbs of trail mix
4.5 divided by 6= .75 lbs each hiker.
SA: 2xLxW + 2xWxH + 2xLxH
SA: 2x4.5x20 + 2x4.5x23 + 2x20x23
SA: 180 + 207 + 920
TSA: 1307cm2 (squared)
Answer:
B. 
; 
Step-by-step explanation:
According to the statement, we find that the following two conditions must be observed:
(Eq. 1)
(Eq. 2)
Since the difference between two even numbers leads to another even number. Hence, 
must be an even number and the correct answer is B.
You have 2 options.
I will show you the most efficient one, but later I will tell you the other.
-4x+6y=12
6y=4x+12
y=4/6x+12
y=2/3x+12
This tells us the point (0,12) as 12 is where it meets the y-axis (that is why you add it)
And then using the slope, 2/3 we can get (2,15) (which is up 3, right 2)
Just graph those, I would show you exactly, but I cannot add attachments sadly.
The other way (which I won’t show it all as the results would end out with the same line) is to fill in x, then y, with 0
So -4*0+6y=12 which means x=0 and you are solving for y and -4x+6*0=12 which means y=0 and you are solving for x
