Answer:
12
Step-by-step explanation:
You need to use PEMDAS
No Parenthesis
4^2 is 16, since 4 * 4 = 16
Now the equation is 24 - 16 + 2*2
2 * 2 = 4
24 - 16 + 4
24 - 16 = 8
8 + 4 = 12
Hope this helps
Those are called "even numbers".
Also, I guess, "multiples of 2" .
Answer:
28.26658805 (I included every digit in case your teacher needs you to round)
Step-by-step explanation:
In order to find x, we need to isolate x by subtracting 15^2 and taking the square root of both sides.
Thus, we have:

Freya begins started with 200 yards.
Freya then increased her distance by adding five yards a day for two days.
x = 200 + (n - 1)5.
<em>[x = The distance Freya sprints on day 21]</em>
x = 200 + (21 - 1)5
x = 200 + (20) 5 = 300 yards
