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.
Im guessing this is a rectangle? If so it would be
16+16+25+25
32+50
82 is the perimeter
Y=2/3x-2
to find intercepts, substitute 0 into y and solve for x = x intercept is (3,0) and repeat for y. substitute 0 into x to get y intercept of (0,-2)
its 14n+21. 7×2n is 14n, and 3×7 is 21
Y=145, I’m not sure about X
