Zero.
Anything times zero is zero.
-20 * -10 = 200
200 * -1 = -200
-200 * 0 = 0
The answer is 14/3 or 4 and 2 thirds
Answer: x = - 12
8x + 45 = 10x + 69
⇔ 10x - 8x = 45 - 69
⇔ 2x = -24
⇔ x = -12

Step-by-step explanation:
complementary angles, when added, equal 90 degrees
so if 1 angle is x, then the other angle, its complement, is 90 - x.
x - 18 = 90 - x
x + x = 90 + 18
2x = 108
x = 108/2
x = 54
90 - x = 90 - 54 = 36
so one angle is 54 and its compliment is 36
