The answer for this equation is -2
Step-by-step explanation:
Here we can see it is a quadrilateral so
x + 108° + 65° + 53° = 360° ( being sum of angles of quadrilateral)
226° + x =360°
x = 360° - 226°
Therefore x = 134°
The expression - x - 9x^2 + 12x^2 + 7 has 4 terms:
-x, -9x^2, 12x^2, 7
Like terms are:
-9x^2, 12x^2
Step by Step :
1. 9(2j + 7 + 5j)
2. (9)(2j) + (9)(7) + (9)(5j)
3. 18j + 63 + 45j
Answer: 63j + 63
