Here is the process:
120/ 2 = 60
60 / 2 = 30
30 / 2 = 15
15 / 3 = 5
Notice that 2, 3 and 5 are all prime numbers
So, 120 = 5*3*2*2*2
The length would be 10 inches.
to find perimeter, you add length+length+width+width.
since both widths and both lengths have to be the same, u add the width 2 times or 7+7=14.
next u subtract 14 from 34 or 34-14=20.
since u still have 2 lengths that are equal, u divide 20 by 2 or 20/2=10
hope this helps! :)
If the line is parallel, the slope must also be 1/3.
Plug in the coordinates of (0,-9) into y=1/3x+b:
1) -9=(1/3)(0)+b
2) -9=0+b
3) b=-9
Answer:
y=-2/5x + 3 is the eq of the line
