Answer:
B.
Step-by-step explanation:
Since i is in the denominator, if i = 0, then the result will be undefined. Therefore, B cannot be a value of θ.
X+2y
Plug in the variables
4+2(7)
4+14
x+2y=18
It doubles every 4 hours, so after 24 hours there will be 6 doublings.
2^6 = 64
So, the population will be (3,000,000 * 64) or 192,000,000 in 24 hours.
The answer is B.
Answer:
B.) 2(5x-4)(x+1)
Step-by-step explanation:
10x^2+2x-8
= 2(5x^2 + x - 4)
= 2(5x^2 + 5x - 4x - 4)
= 2[5x(x + 1) - 4(x + 1)]
= 2(5x-4)(x+1)
