Answer is A. first option
<span>x < –3; y ≤ –x – 1</span>
Answer: 4 • (2x - 7) • (x + 3)
Step-by-step explanation:
(4x+12)(2x-7)
8x²-28x+24x-84
8x²-4x-84
10.8 or 10.9
Round about these points
9 is itself a multiple of 3, so the least common multiple of 3 and 9 is 9 itself
We can use following formula
Now, we need to find sin(2A).
Because, the angle A is in the 1st quadrant, and cos(2A) is negative, that means that the angle 2A is in the 2nd quadrant and sin(2A) is a positive number,so sin(2A) = 4/5.
sin(2A) = 4/5
cos(2A) = -3/5
