Answer:
x=4
Step-by-step explanation:
Answer:
Cindy's error is that an integer is not always negative
In the proof given, BC║AD and CD║BA because: B. slopes of opposite sides are equal.
<h3>What is the Slope of Parallel Lines?</h3>
If two lines are parallel, they will have the same slope value,.
Slope = rise/run.
Slope of BC = rise/run = -2/5
Slope of AD = -2/5
Slope of BA = rise/run = -6/1 = -6
Slope of BA = rise/run = -6/1 = -6
Therefore, we can conclude that BC║AD and CD║BA because: B. slopes of opposite sides are equal.

First you would divide by 2 in both sides
P/2 = l + w
Then you would subtract w from both sides
P/2 - w = l
This is the easiest method do isolate l
You can also distribute the 2 to ( l + w) first
P= 2l + 2w
Then subtract 2w from both sides
P - 2w = 2l
Then you would divide by 2
(P - 2w) / 2 = l
P/2 - w = l
