Answer:
2.8a²+0.9a - 1.2
Step-by-step explanation:
Given the expression 0.3(3a-4)-0.05(8a)(-7a)
Expand using the distributive law
0.3(3a-4)-0.05(8a)(-7a)
0.3(3a)-0.3(4)-0.05(8a)(-7a)
0.9a-1.2 - 0.05(8a)(-7a)
0.9a - 1.2 + 2.8a²
Rearrange
2.8a²+0.9a - 1.2
Hence the required expression is 2.8a²+0.9a - 1.2
When the first number increases by one the second number is added by 4's. So from the first part to the second it added 4 then from the 2nd to the 3rd it skips adding 8 to then just add 12. Then from the 3rd to the 4th it skips adding 16 and adds 20. So the next set of numbers would be (4,64) because it skips adding the 24 and adds the 28.
Hope this helps and is not to confusing :)

Answer:</h2>
There was a total loss of $150.00 over those 6 days
<h2>
Step-by-step explanation:</h2>
1 - Simplify the word problem
A store makes a loss of $25 per day for 6 days
2 - Write a statement for it
d = days
t = total loss
25d = t
3 - Plug in the days for d
25(6) = t
150 = t
t = $150
There was a total loss of $150.00 over 6 days
Hope this helps :)
