Answer:
The lines DE and BC have the same slope, therefore the two lines, DE and BC, are parallel
Step-by-step explanation:
To prove that DE is parallel to BC, we have;
The slope, m of the lines DE and BC are found from the following equation;

Where;
(x₁, y₁) and (x₂, y₂) = (b, c) and (a + b + c) for DE, we have;

Where we have (x₁, y₁) and (x₂, y₂) = (0, 0) and (2a, 0) for BC, we have;

Therefore, because the lines DE and BC have the same slope, the two lines DE and BC are parallel.

=31.25
35-31.25=3.75
The answer is 3.75cm³

Answer:
In Point Slope Form: y+6=4(x-1)
Step-by-step explanation:
<u>First you have to find the points given which are:</u>
<u>Label the points x1, y1, x2, and y2</u>
- It already gives you the slope which is 4.
<u>Plot the points in the equation of Point Slope Form:</u>
<em><u>y1-y2=m(x-x1)</u></em>
<u>Simplify: y1-6=4x-4</u>
<u>It doesn't ask you to simplify but why not! </u>
