Answer:
Not sure exactly which equivalent expression you are looking for but my goal would be to write it without the negative exponent.
Step-by-step explanation:
They have the same exponent and it is multiplication.
There is a law of exponent that says 
.
So we have 
equals 
.
Let's simplify (4*7)^(-2).
Since 4*7=28, we can say 
.
Some people really hate that negative exponent. All that - in the exponent means is reciprocal. So 
.
Answer:
Day 1: 12 is 40% and 18 is 60%
Day 2: 14 is 47% and 16 is 53%
Day 3: 13 is 43% and 17 is 57%
as for the second question, the reason why it's different for each day is probability, the probability can change with literally every movement like how hard you fling it or if there's outside interference like the wind.

Answer:
-3a-12
Step-by-step explanation:
3(-2a-4)+3a
-6a-12+3a
-6a+3a-12
-3a-12
If you would like to simplify <span>(-2)-3 -8 - 8 and 6x - 2, you can do this using the following steps:
</span><span>(-2)-3 -8 - 8 = - 2 - 3 - 8 - 8 = - 5 - 8 - 8 = - 13 - 8 = - 21
6x - 2 = 2 * (3x - 1)
The correct result would be - 21 and </span><span>2 * (3x - 1).</span>
To graph the absolute value graph the function y=f(x). Anything above the x- axis, stays above it.
