Answer: 7
Step-by-step explanation:
2−(−4)+3+(−6)−(−2)2
solution:
– x – = +
– x + = –
= 2−(−4)+3+(−6)−(−2)2
= 6 + 3 + ( – 6) – ( 2 ) 2
= 9 + ( –6 ) – ( –2 ) 2
= 3 – (–2)2
= 3 – ( –4 )
= 7
Answer: B Linear
Step-by-step explanation:
It wouldn't be exponential because there isn't exponent, and it won't be rational because there is no fraction, and it is not quadratic. Hope this helps :)

In 386750.36 years the Carbon - 14 will be 20 g in the substance
Step-by-step explanation:
Here A = 20 g
The given equation is,
A= 25e - 0.000124t
We need to find the value of t
20 = 25e - 0.000124t
20 - 25e = - 0.000124t
25e - 20 = 0.000124t
(25e - 20 ) / 0.000124 = t
t = (25e - 20) / 0.000124
t = (65.957 - 20) / 0.000124
t = 45.957 / 0.000124
t = 386750.36 years
