Answer: 5x - 1
Step-by-step explanation: 3x + 2x = 5x and -6 + 5 = -1, so 5x - 1.
We have the following expressions:
x = 3 + 8i
y = 7 - i
-x * y = (- 3 - 8i) * (7 - i) = -21 + 3i - 56i - 8 = -29 -53i
2x-3y = 2 (3 + 8i) - 3 (7 - i) = 6 + 16i - 21 + 3i = -15 + 19i
-5x + y = -5 (3 + 8i) + (7 - i) = -15 - 40i + 7 - i = -8 -41i
x * 2y = (3 + 8i) * (14 - 2i) = 42 - 6i + 112i + 16 = 58 + 106i
Answer:
-x * y = -29 -53i
2x-3y = -15 + 19i
-5x + y = -8 -41i
x * 2y = 58 + 106i
Both angles added together equal 180 degrees.
B = 180 - 45 = 135 degrees.
Answer:
41 purple marbles
Step-by-step explanation:
x= amount of purple marbles
3x+x=164
4x=164
x=164/4=41
