For this case, we have initially both plants are 3 cm tall.
If a month later the plant A is 7 cm higher, it means that its height will be:

If they tell us that plant B is half the height of plant A, that means:

Answer:
5 centimeters
Answer:
X=84
Step-by-step explanation:
let x be the first integer, then
:
x + (x+1) + (x+2) + (x+3) + (x+4) + (x+5) = 519
:
6x + 15 = 519
:
6x = 504
:
x = 84
area of circle = pi * radius^2
radius = sqrt(area/pi) = sqrt(45/3.14)
radius = 3.78
round up
radius = 4 inches
