1 answer:

8 0

$(4x + 3) + ( - 7x + 5)$
Remove unnecessary parenthesis

$4x + 3 + ( - 7x + 5)$
When there is a "+" in front of the parenthesis the expression remains the same

$4x + 3 - 7x + 5$
Collect the like terms by subtracting their coefficients

$(4 - 7)x$
Calculate the difference
$- 3x$
$- 3x + 3 + 5$
Add numbers
$3 + 5 = 8$
Answer:
$- 3x + 8$

So, 0.5^5 is 0.03125
multiply that by 125 and get your answer.
*3.90625* (4)
just saying, I got the 0.5^5 thing because 5 is the number of half-lives (x) and 0.5 is the rate of loss (or whatever its called).
If it were to gain, you would put 1.5
