<span>The number in this question would be
time= 3 months
bank account change= -12 (since it taken)
</span><span>change in bank account each month= bank accout change / time = -12/3 = -4
</span>Since you are asked "equation that represents the change in Scott's bank account each month." Then the answer should be
-12 / 3 = -4
(-12) (3) = (-4)
Idk for sure but you have to do 6x6x3.14 and then add 271.4
X^2 - 25 = 0
Add both sides by 25
x^2 = 25
Take the positive and negative square root.
x = 5
OR
x = -5
Have an awesome day! :)
A quick way to do this is:

Therefore the temperature rose 6 degrees Celsius. I hope this helps! =)
