Answer:


Step-by-step explanation:
Quadratic Equation given:

Start dividing both sides by 6.



Once, 



Solving 

Then,




700/10 = 70
A heart beats 70 times in a minuet.
70 * 2 = 140
It takes 2 minuets for a heart to beat 140 times.
600300 or 6.003x10^5
3.000= 3 , 6.000= 6
3 x 10^2 = 3 x 100 = 300
6 x 10^5 = 6 x 100000 = 600000
600,000 + 300 = 600300
