A side is 4t so A=400=16t^2 by definition. Thus t=5 which produces an area of 400 since [4 (5)]^2=20×20=400.
I think it is -3/4 im pretty sure
4(-b-4)
Hope this helped :)
Answer:
She started with 200 stamps
Step-by-step explanation:
Set up the following equation for this segment:
x is segment AB's length, and 3x is segment BC's length. 20 is segment AC's length.
Combine like terms:
Divide both sides by 4 to get x by itself:
x will equal 5.
Plug this value into the values for both segments:
Segment AB:
Segment AB is 5 inches long.
Segment BC:
Segment BC is 15 inches long.
