Answer:
-3 sqrt 2 or -4.242640687
Step-by-step explanation:
The equation for this is 100,200(2)^n where n is the number of years
so in 3 years the population will be 100,200(2)^3 = 801,600
Answer:
x = 45
Step-by-step explanation:
Corresponding sides of similar triangles will be in same ratio.
Cross multiply
x*28 = 20*(x+18) {Use distributive method}
28x = 20x + 360
28x - 20x = 360
8x = 360
x = 360/8
x = 45
