Answer:
D) 3/15
Step-by-step explanation:
(-2/5) - (-9/15) = (-6/15) - (-9/15) = (-6/15) + (9/15) = 3/15
Answer:
2x³ + 3(3x - 4)(x + 1)
Step-by-step explanation:
(2x³ + 7x² + x) + 2(x² - 2x - 6)
2x³ + 7x² + x + 2x² - 4x - 12
2x³ + 9x² - 3x - 12
2x³ + 3(3x² - x - 4)
2x³ +3(3x - 4)(3x + 3)/3
2x³ + (3x - 4)(3x + 3)
2x³ + 3(3x - 4)(x + 1)
The answer to the above question can be explained as under -
We know that, the sum of angles of triangle is 180°.
So, vertex angle plus base angles are equal are equal to 180°.
Let the vertex angle be represented by "v" and base angles be represented by "b".
Thus, v + b + b = 180°
So, v + 2b = 180°
Next, the question says, the vertex angle is 20° less than the sum of base angles.
Thus, 2b - 20° = v
<u>Thus, we can conclude that the correct option is A) v + 2b = 180°, 2b - 20° = v</u>
