<u>Given expression:</u>
<u>Answer options for equivalent expression:</u>
A. (2x - 1)(x + 4)= 2x² + 8x - x - 4 = 2x² + 7x - 4
B. (2x + 1)(x - 4) = 2x² - 8x + x - 4 = 2x² - 7x - 4
C. (2x + 1)(x + 4) = 2x² + 8x + x + 4 = 2x² + 9x + 4
D. None of these
Answer:
1: 98
2: 82
3: 98
4: 82
Step-by-step explanation:
So 2 is 82deg then the opposite is also 82 so 4 is 82deg
Then 82+82 = 164deg, and we remain with 360deg-164deg which is = 196.
Since the other two angles will be equal (they are opposite each other) we can decide 196/2 = 98
So 3 and 1 are 98deg
Answer: 12x² + 11x - 15
fg = (4x - 3)(3x + 5) = 12x² + 20x - 9x - 15 = 12x² + 11x - 15
