I have no idea why you deleted my answer i am sorry if you are mad at me for something. hopefully it was right though.
The real part of the result is the product of the real parts of the factors and the product of the imaginary parts:
a = 15*6 - (-4)(-3) = 90 -12 = 78
_____
You can treat this the same as any other product of binomials except that i² = -1.
... (15 -4i)(6 -3i) = 15(6 -3i) -4i(6 -3i) = 15·6 -15·3i -4·6i +4·3i²
... = 90 -45i -24i +12i² = (90 -12) -69i = 78 -69i
Answer:
let the missing length =x
Then,by similiarty of triangle
<h2>X = 8 mark me as brainliest ❤️</h2>
The answer is 13/4.
i use the formula y=mx+b and i plug in the # and then i added 6. and so on
