Answer:
x= -8
collect like term than divide both sides
6x-4x = -20+4
2x= -20+4
2x=-16
x= -8
Divide both sides of -105=-5g by -5. You'll get g = -105 / (-5), or g = 21.
Answer:
SAS
Step-by-step explanation:
Divide actual distance by the distance of the scale miles
39 miles / 13 miles = 3
Multiply that by the scale inches:
2 inches x 3 = 6 inches.
The answer is 6 inches.
Take first derivative of area function and set it to zero
da/dx=24 - 2x=0
Now it is set to zero add -2x to both side
24 - 2x = 0
24 = 2x
Now divide by 2 in both sides
12 = Width
Your width now is 12
Plug 12 into you equation like this:
24 (12) - 12^2= A
288 - 144 = A
144 = Area
144 feets is the maximum area using the width 24
