Can you show the graph or the problem?,
To find the area, you of course multiply your length by width (40 x 20), which would get you your area of 800 ft squared. hope this helps!
Answer:
w(t-4)=t^2-9t+20
Step-by-step explanation:
w(t)=t^2-t
w(t-4)=(t-4)^2-(t-4)
w(t-4)= t^2-8t+16-t+4
w(t-4)=t^2-9t+20
Answer:
200 pencils and 120 pens
Step-by-step explanation:
Let the number of pencils be x while pens be y.
Considering the cost of whole purchase then, we get the equation
0.5x+y=220
Considering the number of items bought, then the equation is
x-y=80
Adding the two equations then we have
1.5x=300
x=300/1.5=200
Consideeing that x-y=80 and x is 200 then
200-y=80
y=200-80=120
Therefore, the pencils were 200 and pens 120 pieces
