I think you just do 133/4 -2 unless I’m mistaken
Answer:
the answer is x = 2 or B, hope this helps
Step-by-step explanation:
Answer:
4 by 3 matrix.
Step-by-step explanation:
In the matrix, there are 4 rows of numbers and 3 columns of numbers.
For the first question the problem is simple. He is essentially going around 2 sides of a triangle, instead of along the hypotenuse. You would have to use Pythagoras' theorem for the real answer, a^2 + b^2 = c^2. However, for question 15, i don't know, I'm pretty sure this is an American question and I'm British, I don't believe I have ever encountered ordered pairs, or at least i don't remember learning them. Hope this helps ;)
(10+3i)*(5-2i) =
50 - 20i + 15i - 6i²
i² = -1
50 - 5i - 6*(-1) =
50 - 5i + 6 =
56 - 5i
