Given: D is the midpoint of AB; E is the midpoint of AC.
Thepotemich [5.8K]

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;

Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}

Where;

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

Slope, \, m =\dfrac{c - c}{a + b-b} = 0

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

Slope, \, m =\dfrac{0 - 0}{2a-0} = 0

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

How do i calculate root equations
WITCHER [35]
It by root you mean radical equations, well then I can’t help you there, as there is too much stuff to cover.

If you mean zeros, then to find the root of a function you just find the zeros.
