Answer:
The answer is 2
As we can see lineAB is the same as lineCD
<span> 2000=400+1/6x
subtract 400 from each side..... 400-400 cancels out....2000-400=1600
1600=1/6x
multiply by recipricol, 1600*6/1= 9600........1/6*6/1 cancels out
9600=x
You must sell $9600 worth of stuff to earn $2000.

zm= a+b/a, for a
Switch sides to have a on left side
a+b/a=zm
Now multiply both sides by a
A+b= zm(a)
A+b= ama
Now subtract azm both sides
A+b-azm=0
Subtract b both sides
A-azm= -b
Factor out a from ask
A(1 -zm)= -b
Divide each term by 1 - zm to get
A= - b/1-zm
Answer: Length = 10cm
Width = 6cm
Step-by-step explanation:
First and foremost, we should note that
1 meter = 100 cm.
Therefore,
Length = 5m = 500 cm
Breadth = 3m = 300 cm.
Since Elena wants to make a scale drawing of 1 to 50, then
Length = 500 cm / 50 = 10 cm
Breadth = 300 cm / 50 = 6 cm.
Therefore, the length of the scale drawing will be 10 cm and the width of the scale drawing will be 6cm.

(fg)(x)=f(x)g(x)=(2x^2−3)(x+4)=2x^3+8x^2-3x-12
