Let us assume PQ || BC.
Then, by Basic Proportionality Theorem, we get,
AP/PB = AQ/QC
=> x/(x+7) = (x-3)/(x+1)
=> x (x+1) = (x+7)(x-3)
=> x^2 + x = x^2 - 3x + 7x - 21
=> x = 4x - 21
=> -4x + x = -21
=> -3x = -21
=> 3x = 21
=> x = 21/3
=> x = 7
Therefore, for PQ||BC the value of x should be 7
(2 + 3i) - (5 - 7i)
2 + 3i - 5 + 7i
2 - 5 + 3i + 7i
-3 + 10i - final answer
Answer:
-1 1/4
Step-by-step explanation:
-4 1/2 is converted to -4 2/4
And -4 2/4 + 3 1/4 = - 1 1/4
