Answer: 6
Step-by-step explanation: 12x+3=75
-3 -3
<u>12x</u>=<u>72</u>
12 12
x=6
If we let x represent the length, then the width is (4x-48), and the area is ...
x(4x-48) = 256
This is neatly solved graphically to find x = 16. (x=-4 is an extraneous solution)
The rectangle's length is 16 cm.
The expanded form for 15,409 is 10,000 + 5,000 + 400 + 9
Answer:
we don't see the graph, so we cannot tell anything.
