Answer: (x^2+2)(2x^2-3)
Step-by-step explanation:
2x^4 + x^2- 6
= 2x^4+4x^2-3x^2-6
= 2x^2(x^2+2)-3(x^2+2)
= (x^2+2)(2x^2-3)
Answer:
D 5.46 x 10^10
Step-by-step explanation:
Recall that speed is the rate of change of distance with time and may be expressed mathematically as
speed = Distance/time
Distance = speed * time
Hence given that the speed of light
= 3 × 10^8 meters per second
Time taken for light to travel between the given distance
= 1.82 × 10^2 seconds
substituting the given values
Distance = 3 × 10^8 * 1.82 × 10^2
= 5.46 * 10^(8+2)
= 5.46 * 10^10 meters
Answer:
y = (2/7)x -12 (Answer Choice B)
Step-by-step explanation:
Take the given values ( m=2/7 and y-intercept (0,-12) ) and substitute them into y = mx + b:
y = (2/7)x -12
