Answer: 3^6 so D or C
Step-by-step explanation:
When dividing two squares, you minus the number
Answer:
a = 5 or a = -5
Step-by-step explanation:
Answer:
The same number was not added to both sides.
Step-by-step explanation:
The same number was not added to both sides.
In line 2, 6 was added to the left side and 78 was added to the right side.
Using an exponential function, it is found that it takes 18.6 days for 80% of the material to decay.
The amount of a substance after t days is modeled by:
In which:
- k is the decay rate, as a decimal.
- A(0) is the initial amount.
The half-life is of 8 days, hence 
, and this is used to find k.
Hence:
The time it takes for 80% of the material to decay it t for which 
, hence:
It takes 18.6 days for 80% of the material to decay.

An appropriate measure for ∠CDE would be
∠CDE = ∠ADE - ∠ADC
<h3>How to check for the appropriate measure of CDE.</h3>
we have the following angles as parallel BC¯, DE¯, and FG¯ also CD¯, EF¯, and GH¯.
The angles that we have to check in order to measure would be
∠ABC, ∠AEG, ∠ADC, ∠AHG, ∠ADE, ∠AFE, ∠AHG.
