Answer:
x=10^{\frac{2}{3}}-5
Step-by-step explanation:
Area of right-angled triangle is given by;
Area, A = 1/2 *b*h, Where b=base, h=height
Therefore,
A1 = 1/2bh = 16 in^2
A2 = 1/2 (2b)(2h) = 2bh
Ratio of increase = A2/A1 = {2bh}/(1/2bh} = 4 (the area is increased 4 times)
The,
A2 = 4*16 = 64 in^2
Therefore,
The area is increased by (64-16) = 48 in^2
It is 15 meters long on each side.
You find the square root of 225 which is 15, because when you multiply 15 by 15 you get 225.
It would be C, because there are 700,000 people and with A, B, and D there are more people than there are the original population.
Your answer should be C sorry if i'm wrong, hope it helps tho
