1.3 is the least because ur supposed to add a zero so they can all be the same place value
No. To test whether a graph is a function or not you do the vertical line test where if a vertical line touches more than one point it is not a function
2 x 117
3 x 78
6 x 39
9 x 26
13 x 18
Okay, so you know that the perimeter of the pen is 28 feet. Now we need the separate side lengths.
P = 28 ft.
Length = x
Width = (1/2)x + 2
So now we can plug in the little equations of length and width into a perimeter formula:
2(x) + 2((1/2)x + 2) = 28
Distribute the 2's and solve as needed.
2x + x + 4 = 28
3x + 4 = 28
3x = 24
x = 8
To find the width, just plug in 8 for x in our little equation:
(1/2)(8) + 2
= 6
So, the length is 8 feet and the width is 6 feet.
