<span>Simplify (8 + 7i) + (2 –i)
</span>answer:10+6i
Given:
Area of a triangle = (h*b) / 2
Area of smaller triangle = (4cm * 4cm) / 2 = 16cm² / 2 = 8 cm²
Area of larger triangle = (6cm * 10cm) / 2 = 60cm² / 2 = 30 cm²
30cm² - 8cm² = 22cm²
Probability that the point is inside the large triangle but outside the small triangle:
22cm² / 30cm² → 11/15 → 0.73 or 73%
You take the three zeros and put them back with the x s
(x-6)(x+5)(x-2) they are reversed when you put them back in
multiply the first two and get
simplify to

Multiply it out again and get

finally simplify and get
So the answer is the first one
