Answer: 2x + 40 = 150
Step-by-step explanation:
Jane has 150 feet of fencing. 40 feet will go for the portion opposite the house, The remaining fencing will go for the two sides of equal length x. That makes 2x for both. So:
<u>2x + 40 = 150</u>
[x = 55 feet]

Step-by-step explanation:
<u>Dilations</u>
Given a point A(x,y) and a scale factor k the dilated image of A, called A' is calculated as A'=(kx,ky), assuming the same scale factor is applied in both axes.
The pentagon ABCDE was dilated to create pentagon A'B'C'D'E'. To find the dilaton rule used, we must find two clear points where the coordinates of both axes can be easily read from the graph.
Point C(-2,0) maps to C'(-5,0). This gives us the scale factor for the x-axis of -5/(-2)= 5/2.
The y-coordinate of E is 2 and the y-coordinate of E' is 5. This gives us the same scale factor for the y-axis of 5/2.
Thus, the rule to dilate the pentagon is:
B 
7 because you have to round 6 to 7 from the former seven and seven is bigger than 4 so the 6 would become a
