see below
Step-by-step explanation:
<h3>Proposition:</h3>Let the diagonals AC and BD of the Parallelogram ABCD intercept at E. It is required to prove AE=CE and DE=BE
<h3>Proof:</h3>1)The lines AD and BC are parallel and AC their transversal therefore,
2)The lines AB and DC are parallel and BD their transversal therefore,
3)now in triangle ∆AEB and ∆CED
therefore,
hence,
- AE=CE
- DE=BE

Multiply and simplify (3 + i)(4 + 2i)
(3 + i)(4 + 2i) = (3*4) + (3*2i) + (4*i) + (2i*i) = 12 + 6i + 4i + 2i^2
i^2 = -1
12 + 6i + 4i + 2i^2 = 12 + 6i + 4i -2 = 10 + 10i
Use the imaginary number i to rewrite the expression:
